In contrast to Abrams et al. (2), the 2 Hamiltonian of Brown et al. (12)

s used in our work along with a partial list of matrix elements provided by

miot et al. (13). The necessary additional higher order matrix elements were

nerated by algebraic matrix multiplication using the Maple program. Melen

al. (1) also used Browns effective Hamiltonian and we checked our term

lues against theirs. The main difference between our analysis and that of

rams et al. (2) lies in the values of the spinorbit constants A. Our con-

nts now agree well with those derived by Copeland et al. (3) for the higher vels.

Cosby et al. also found a problem with the ground state constants of OH and

ried out a refit of the existing data (14).
