NAME: biphenyl, phenylbenzene
FORMULA: (C6H5)2
AUTHOR(YEAR): McLaughlinClark(1978)
T: 298K
λ: 142.3-285.8nm
BIBLIOGRAPHY: T.G. McLaughlin and L.B. Clark, "The electronic spectrum of biphenyl", Chem. Phys. 31, 11-18 (1978); DOI: 10.1016/0301-0104(78)87021-9
COMMENTS: "Zone refined biphenyl was placed in a 25 cm absorption cell of a 1-meter vacuum spectrometer, and the absorption spectrum was recorded at a variety of temperatures. Due to very uncertain vapor pressure data there is a large uncertainty in the absorption coefficients. We have chosen to simply average the reported vapor pressures to obtain our absorption values."

Room temperature assumed

Extinction coefficients vs. wavenumber as plotted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-21) vs. wavelength
