- 中文摘要: Intermolecular energy transfer in liquid bromoform and d-bromoform was investigated by help of picosecond IR and Raman spectroscopy. For a comprehensive interpretation of the corresponding results the study of C-H bending overtone (2n4) relaxation was necessary; the effective vibrational lifetime of this vibrational mode was determined to T1 = 3±1 ps. For the intermolecular transfer a dominating process between the intramolecularly equilibrated C-Br stretching modes n2 and n5 of CHBr3 and CDBr3 with a rate constant of 4×1010 s-1 was recognized. Other possible channels, particularly the one between the quasi resonant modes n1(C-D) and 2n4(C-H) were found to be negligible
