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).
