Halpern, B.R. Ramachandran Title: The Electronic Spectroscopy and Photophysics of Saturated Phosphines Journal/Source: J. Molecular Spectroscopy, 151 (1), 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 for the gas phase between 42000 and 54000 cm-1. Absorption maxima (and extinction coefficients) for TMP, TEP, and TPP are 49850 (1.5 x 10^4), 48080 (9.0 x 10^3), and 47620 (6.0 x 10^3) cm-1 (M-1 cm-1).
