Abstract : The 0(+)-0 and 1(+)-0 bands of the a triplet A2 - x singlet A(1) transition of formaldehyde have been reinvestigated using higher resolving power than was available in the earlier work of Raynes. The rotational analyses have been considerably extended, and improved molecular constants for the a triplet A(2) state have been obtained with the aid of a new triplet-singlet computer programme. (sS)R branches of the K = 7- K double prime = 5 and K' = 5 - K double prime = 3 subbands have been ovserved in the 0(+)-0 band using 7 m atm of absorbing gas. The 'perpendicular' transition moment is found to be about 10% of the 'parallel' transition moment. (Author Modified Abstract)
