Irradiation of [Pt(Ns) dien]+ at its charge-transfer maximum produces azide radicals, and presumably transient platinum(m). Similarly, pulse radiolysis experiments on [PtCU] " and [Pt(CN)4] generate transient platinum(i) and platinum(iii) species, whose kinetic properties were investigated. ... 

The first attempt at pure soda-lime glass preparation was a disaster The melt was made in a platinum dish and heated in a 20KW carbon granule furnace equipped with a tap-off transformer and protected by a circuit breaker in the power supply. I had been assured that the furnace would not melt Ferro-Silicon (approx. 1590°C) and was therefore safe for platinum (M.P. 1753 C). I reasoned that the furnace power supply maximum could be 20KW so...

A further rapid one-electron oxidation of the intermediate platinum(m) complex by iron(m) is then postulated.
