T2-Measurement on a Dipole-forbidden Transition of OCS

Abstract

Abstract A double resonance pulse sequence experiment is described allowing the determination of the rotational relaxation time of certain dipole-forbidden transitions. Measurements on the pres­ sure dependence of To for the dipole-forbidden transition J = 0, M = 0 → J = 2, M = 0 of OCS have been performed using a superhet bridge type transient spectrometer. No significant difference of the results is found compared with measurements on the dipole-allowed transitions J = 0, M = 0 → J = 1, M = 0 and J = 1, M = 0, ± 1 → J = 2, M = 0, ± 1.
