Infrared, UV/Vis, and W-band EPR spectroscopic characterization and photochemistry of triplet mesitylphosphinidene
(Chemical Equation Presented) Monitoring the cleavage of phosphiranes 1 and 2 by using a variety of low-temperature and time-resolved spectroscopic techniques has shown that triplet mesitylphosphinidene (3) is the principal product of this photolytic reac

The EPR Spectrum of Triplet Mesitylphosphinidene: Reassignment and New Assignment
Low-temperature UV-photolysis of mesitylphosphiranes under highly anaerobic conditions leads to the formation of the triplet mesitylphosphinidene (MesP). The recorded X-band EPR spectrum of triplet MesP and the derived zero-field splitting parameter D=4.116 cm?1 differ significantly from those reported previously for this intermediate. New magnetic parameters of mesitylphosphinidene are discussed along with the results of DFT calculations.
