Abstract
Photoabsorption and fluorescence cross sections of Cd(CH3)2 were measured in the 115–270 nm region using synchrotron radiation as a light source. Vibrational structures superimposing on absorption continua were observed in the 140–230 nm region. Fluorescence appears at excitation wavelengths shorter than 184 nm. Fluorescence produced at 123.6, 147, and 157.5 nm was dispersed to identify the emission to be mainly from excited Cd (326.1 nm). Emissions from excitation of Cd(CH3)2 at 157, 193, and 248 nm via a multiphoton excitation process were investigated.
