DATAFILE: (CH3)PH2_Halmann(1963)_296K_185-210nm(meas).txt
NAME: methylphosphine
FORMULA: (CH3)PH2
AUTHOR(YEAR): Halmann(1963)
T: 296K
λ: 185-210nm(meas)
BIBLIOGRAPHY: M. Halmann, "Far-ultraviolet absorption spectra of phosphorous compounds in the gas phase", J. Chem. Soc. 1963, 2853-2856 (1963); DOI: 10.1039/JR9630002853
COMMENTS: Absorption measurements using Beckman, Hilger, Cary, and Unicam spectrophotometers

The data points plotted in Fig. 1 (extinction coefficients vs. wavelength) have been digitized and the extinction coefficients have been converted to absorption cross sections (conversion factor 3.8235×10-21)

For the absorption maxima at 187 and 201 nm the extinction coefficients εmax =1500 ± 200 and 130 ± 30 L mole-1 cm-1 are reported, which correspond to σmax = (5.7 ± 0.8)×10-18 and (5.0 ± 1.1)×10-19 cm2 molecule-1
