Abstract
The Doppler-free polarization spectrum was measured for the B-1 Pi-X-1 Sigma(+) band system of the (KLi)-K-39-Li-7 molecule. The Dunham coef ficients describing the X state and f-parity levels of the B state are reported. Numerous transitions were observed for the (KLi)-K-41-Li-7 and (KLi)-K-39-Li-6 isotopomers, the latter ones displaying anomalous isotopic shifts. The anomalies are discussed in terms of mass-independ ent 'reduced' Dunham coefficients and mass-scaling factors. (C) 1998 E lsevier Science B.V. All rights reserved.
