The WNiP cluster was oxidised by a peroxide to yield a μ-coordination, where each phosphorus atom is bound to three metal atoms.
|
Phosphorus monoxide is a free radical with phosphorus double bonded to oxygen with phosphorus having an unpaired
|
valence electron.
|
The bond order is about 1.8.
|
The P=O bond in PO has a dissociation energy of 6.4 eV.
|
The bond length of the PO double bond is 1.476 Å, and free PO shows an infrared vibrational frequency of 1220 cm due to the stretching of the bond.
|
The free radical nature of PO makes it highly reactive and unstable compared to other phosphorus oxides that have been further oxidized.
|
The visible to ultraviolet spectrum of phosphorus monoxide has three important bands.
|
There is a continuum band near 540 nm.
|
The β-system near 324 nm is due to the DΣ→Π transition.
|
The γ-system has bands near 246 nm due to a AΣ→Π transition.
|
Peaks in this band occur at 230, 238, 246, 253, and 260 nm in the ultraviolet.
|
All these bands can be emission, absorption, or fluorescence depending on the method of illumination and temperature.
|
There is also a C'Δ state.
|
The γ-system band can be broken down into sub-bands based on the different vibrational transitions.
|
(0,0), (0,1) and (1,0) are designations for the sub-bands produced by the transition between two vibration states, as the electronic transition occurs.
|
Each of these contains eight series termed branches.
|
These are P, P, Q, R, P, Q, R and R.
|
The ionisation potential of PO is 8.39 eV.
|
When ionised, PO forms the cation PO.
|
The adiabatic electron affinity of PO is 1.09 eV.
|
On gaining an electron the PO ion forms.
|
r in the ground state is 1.4763735 Å.
|
The dipole moment of the molecule is 1.88 D. The phosphorus atom has a slight positive charge calculated as 0.35 of the electron.

Italian submarine Argonauta (1931)
|
Argonauta was the lead ship of her class of seven submarines built for the (Royal Italian Navy) during the early 1930s.
|
The "Argonauta" class was derived from the earlier s. They displaced surfaced and submerged.
|
The submarines were long, had a beam of and a draft of .
|
They had a operational diving depth of .
|
Their crew numbered 44 officers and enlisted men.
|
For surface running, the boats were powered by two diesel engines, each driving one propeller shaft.
|
When submerged each propeller was driven by a electric motor.
|
They could reach on the surface and underwater.
|
On the surface, the "Settembrini" class had a range of at ; submerged, they had a range of at .
|
The boats were armed with six torpedo tubes, four in the bow and two in the stern for which they carried a total of 12 torpedoes.
|
They were also armed with a single deck gun forward of the conning tower for combat on the surface.
|
Their anti-aircraft armament consisted of two single machine guns.
|
"Argonauta" was laid down by Cantieri Riuniti dell'Adriatico at their Monfalcone shipyard in 1929, launched on 19 January 1931 and completed the following year.

Geppino Micheletti
|
Geppino Micheletti (July 18, 1905 – December 8, 1961) was an Italian doctor active in Pula at the end of the Second World War, and then in Narni.
|
In 1947 he was awarded the Silver Medal for Civil Valor and the Great Gold Medal of the Municipality of Pula.
|
He is remembered for having operated on the wounded from the Vergarola explosion continuously for over 24 hours on Sunday, August 18, 1946.
|
The son of Giuseppe Michelstadter and Irma Mejer, who was of Jewish origin, Micheletti was a cousin of the Gorizia philosopher Carlo Michelstaedter.
|
He studied in Turin, qualified in Milan, and specialized in surgery in Bologna.
|
He settled in Pula in the 1920s.
|
During the Second World War, from 1941 to 1943 he was director of the 41st auxiliary surgical group stationed in Croatia, and he was decorated with three War Merit Crosses.
|
In the Vergarolla explosion he lost not only his brother Alberto and his sister-in-law, but also his only two children, Carlo and Renzo, ages 5 and 9, who had gone to the beach like many other children for a traditional swimming competition.
|
Carlo's body was found, but only one shoe remained from Renzo.
|
Despite being informed of their fate, he continued to take care of seriously injured and maimed patients for more than 24 hours at Santorio Santorio Provincial Hospital in Pula.
|
Following the peace treaty, Geppino Micheletti left Pula with his wife Jolanda in March 1947, after being commended for duty by the Red Cross as indispensable, and having coordinated the evacuation of hospitalized patients.
|
In June 1947 of the same year he found work in Narni, Umbria.
|
He remained there and practiced surgery for 14 years, until his death following a postoperative embolism.
|
A plaque installed at Rosmini Square ("Piazzale Rosmini") in 2008 in Trieste commemorates Micheletti.
|
Next to the memorial stone commemorating the Vergarola explosion at the Pula Cathedral there is also a small memorial stone with his image.
|
The Croatian Post Office paid tribute to Micheletti in 2010 with a commemorative cancellation.

Kristen Kit (born August 18, 1988) is a Canadian sportsperson, who competes as a coxswain in both women's eights and mixed coxed four rowing events, and who currently rides for UCI Women's Continental Team in road bicycle racing.
|
In rowing, Kit competes in international level events where she has won six medals in eights and coxed fours.

Italian submarine Jalea (1932)
|
Jalea was one of seven s built for the (Royal Italian Navy) during the early 1930s.
|
She played a minor role in the Spanish Civil War of 1936–1939 supporting the Spanish Nationalists.
|
The "Argonauta" class was derived from the earlier s. They displaced surfaced and submerged.
|
The submarines were long, had a beam of and a draft of .
|

|

|
They were also armed with a single deck gun forward of the conning tower for combat on the surface.
|
Their anti-aircraft armament consisted of two single machine guns.
|
"Jalea" was laid down by Odero-Terni-Orlando at their Muggiano shipyard in 1930, launched on 15 June 1932 and completed the following year.
|
During the Spanish Civil War, she unsuccessfully attacked the mail steamer off Barcelona on 25 December 1936.
|
Both torpedoes missed and one of them beached itself without exploding.
|
It was identified as Italian built and proved that Italy was covertly supporting the Nationalists.
|
The submarine was on a patrol off Cartagena when she attacked the Republican destroyers and on 12 August 1937.
|
One torpedo destroyed one of the former's boiler rooms, killing four men and wounding eight and crippling the ship.
|
"Jalea" accidentally surfaced while attacked which allowed observers to determine that she was of foreign origin, not a boat in Nationalist service.
