Halpern, B.R. Ramachandran Title: The electronic spectroscopy and photophysics of saturated phosphines Journal/Source: J. Mol. Spectroscopy, 151, 26-32, (1992); http://dx.doi.org/10.1016/0022-2852(92)90004-8 Data: diagram, table Energy/Wavelength range: ~ 185 - 238 nm (42000 - 54000 cm-1) Resolution: Temperature: 293 K Temperature dependence: no Pressure/Concentration: Phase: gas pH: Comments: The near-UV absorption spectra of PH3 and its trialkylderivatives trimethylphosphine (TMP), triethylphosphine (TEP), and tri-n-propylphosphine (TPP) are reported. PH3 exhibits only end absorption in this region, at 54000 cm-1 the molar extinction coefficient is 4.8 x 10^3 M-1 cm-1. Author to whom correspondence should be addressed: (e-mail address):
