Abstract:
A laser excitation spectrum of the (0, 0) and (1, 1) bands of the CaF A(2)Pi-X(2)Sigma(+) system was recorded. The present set of molecular constants for both A(2)Pi and B(2)Sigma(&plus:) states represents a vast improvement in precision over previously reported values because of the larger number of line position measurements and the use of a more reasonable effective Hamiltonian model which accounts explicitly for the A approximately B interaction via off-diagonal matrix elements. The principal constants (in cm(-1)) are where uncertainties of 1varsigma are given in parentheses. Copyright 1999 Academic Press.
