Photoionization of vibrationally hot CH3 and CF3
Vibrationally hot CH3 and CF3 were produced by the 266  nm photodissociation of CH3I and CF3I, respectively, and probed by single-photon ionization at 118  nm. Comparison of the io...

Importance of vibronic effects on the circular dichroism spectrum of dimethyloxirane
We present a theoretical study on the vibrational structure of a circular dichroism (CD) spectrum using time-dependent density-functional theory in combination with a Franck–Condon-type approach....

Recent measurements [R. Panajotovic, M. Jelisavcic, R. Kajita, T. Tanaka, M. Kitajima, H. Cho, H. Tanaka, and S. J. Buckman, J. Chem. Phys. 121, 4559 (2004)] and calculations [C. Trevisan, A. E. Orel, and T. N. Rescigno, Phys. Rev. A 70, 012704 (2004)] of the elastic electron cross section for C2F4 differ materially from our earlier calculations [C. Winstead and V. McKoy, J. Chem. Phys. 116, 1380 (2002)]. Some of the differences are readily attributed to approximations made in our computations, but an overall difference in cross section magnitude above ca. 10 eV was surprising. Here we report a reexamination of the electron-C2F4 elastic cross section. After eliminating or minimizing various possible sources of error, we continue to predict a substantially larger cross section at higher energies. ©2005 American Institute of Physics
