摘要：
Perturbations in the K = 1 and 3 levels of the (A) over tilde (1)A(u), 4 nu(3) state of acetylene are explained as interactions with levels of the (A) over tilde (1)A(u), 3(1)B(4) (v(3) = 1, v(4) + v(6) = 4) polyad. A satisfactory least-squares fit to the perturbed level structure has been obtained, treating the 4 nu(3) state as an asymmetric top perturbed by isolated K = 1 and 3 levels. Accurate deperturbed rotational constants for the interacting states are presented.
