NAME: 1,4-dimethylbenzene, p-xylene
FORMULA: p-(CH3)2C6H4
AUTHOR(YEAR): Bolovinos(1982)
T: 298K
λ: 139.4-279.5nm
BIBLIOGRAPHY: A. Bolovinos, J. Philis, E. Pantos, P. Tsekeris, and G. Andritsopoulos, "The methylbenzenes vis-a-vis benzene. Comparison of their spectra in the valence shell transition region", J. Mol. Spectrosc. 94, 55-68 (1982); DOI: 10.1016/0022-2852(82)90293-4
COMMENTS: Absorption measurement using a Rank-Hilger 776 monochromator, a McPherson hydrogen light source, a dual-beam sample chamber, and a detection system (spectral resolution 0.25 nm)

Extinction coefficients (in L mol-1 cm-1) vs. photon energy plotted in Fig. 1e have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelength (values for 226 and 228 nm interpolated)

A preliminary report deals with the Rydberg series observed in the region 7-9 eV (138-177 nm):
