A scientific biography of Dr. Timothy J. Lee

Picking up Good Vibrations through Quartic Force Fields and Vibrational Perturbation Theory

“…The late Dr. Timothy J. Lee of the NASA Ames Research Center always said that the harmonic (quadratic) terms generically report six trustworthy decimal places, the cubics four, and the quartics a mere two, a concept that theoreticians have employed for many years. However, Lee’s experience simply found this trend to be largely consistent for most cases. In order to evaluate such a heuristic, the analysis of Tables and should be informative.…”
