Light-induced drift and separation of the components of the mixture 13CH3F + 12CH3F in a continuous IR-radiation field
A light-induced drift was produced as a result of continuous C02-laser radiation on a mixture of isotopic molecules 13CH3F + l2CH3F. An isotopic effect with a separation coefficient of ^ 1.2 was recorded. The variation of the transport cross section as a result of vibrational excitation of molecules was measured quantitatively for the first time. It was found to be equal to 6X 1СГ3 for CH3F.
