My research provides highly accurate Infrared Line Lists and spectroscopic constants for interesting molecules in outer space. These lists and constants can help astronomers and spectroscopists analyze the spectra they acquired in both astronomical observations and laboratory studies, because spectra of many molecules (such as NH3, SO2,etc.) are very complicate and difficult to fully analyze while their spectra can serve as critical tools in the characterizaion of environment on celestial objects.
Combining high quality ab initio potential energy surfaces (PES) and dipole moment surfaces (DMS) with reliable accurate experimental data, we are able to compute complete, reliable IR line lists. These line lists not only reproduce existing experimental data, but more importantly, they provide the most reliable predictions for the spectra region where no experimental data are available. Moreoever, complete and reliable IR line lists can be generated for various minor isotopologues with similar accuracy. Our predictions have been confirmed many times by independent experimental studies.
One example is the CO2 IR spectra at 1.1 um:
Second example is 32S16O2 high-resolution spectra, Ames-296 Predictions vs. Recent Experiments
For larger molecules, we carry out Vibrational 2nd-order Perturbation Theory (VPT2) analysis on highly accurate Quartic Force Fields (QFF) to get reliable spectroscopic constants. A recent example is on cyclic C3H3+, where an IR simulation based on our predicted spectroscopic constants easily match up with observed spectra.
