EFFECTIVE REDUCTION OF WAVE-NUMBERS OF ROTATIONAL AND VIBRATION-ROTATIONAL TRANSITIONS OF LIH X-1-SIGMA(+)

A deformationally self-consistent procedure is applied to reduce the w avenumbers of 594 pure rotational and vibration-rotational transitions of (LiH)-Li-7-H-1, (LiH)-Li-6-H-1, (LiH)-Li-7-H-2, and (LiH)-Li-6-H-2 to 15 unconstrained and 2 constrained parameters with <(sigma)over ca p> = 1.098, sigma = 0.000554 cm(-1), and F = 7.704 x 10(14). The quali ty of the Born-Oppenheimer approximation and the extent of its breakdo wn in LIH are reexamined. (C) 1997 Academic Press.
