Pendular States of Highly Vibrationally Excited Molecules



J Ortigoso, Gerald T. Fraser, Brooks H. Pate


The behavior of coherent field-induced hybrids of field-free rotor states (pendular states) is studied in energy regions where intramolecular vibrational energy redistribution phenomena are important, is studied. The energy region corresponding to the 4Ņ1 band system of HCCF molecules, at approximately 12 800 cm-1, has been chosen as an example. The calculations show that the expectation value of the orientation of molecules prepared in nonstationary pendular bright states exhibits a slow decay to the equilibrium value. Therefore, the molecules substantially conserve their initial orientation after intramolecular vibrational redistribution takes place.
