Marilyn E. Jacox

The late Marilyn Jacox's (NIST staff from 1962 to 2013) research interests concerned identification and derivation of molecular properties of small free radicals, molecular ions, and other highly reactive chemical reaction intermediates using infrared spectroscopic data obtained for these species trapped in solid neon or argon at cryogenic temperatures.

Research projects:

Matrix isolation infrared spectroscopy

Vibrational and electronic energy levels of polyatomic transient molecules
