We present the Floquet method of calculation of multiphoton ionization rate
s from the dressed sigma(g)(+) and sigma(u)(+) states of H-2(+). Our softwa
re allows a determination of ionization rates for a range of laser frequenc
ies, intensities and internuclear separations. The theoretical method is di
scussed and instructions for use of the accompanying computer program, whic
h also produces ionization rates for DC field ionization, are given. (C) 19
