A decade ago, the advent of broadband chirped-pulse Fourier-transform microwave spectrometers revolutionized rotational spectroscopy in the centimeter-wave region [1]. Commercial solution are available in the millimeter-wave ...

The electronic spectra of the resonance-stabilized radical C$_9$H$_9$ isomers \textit{cis}- and \textit{trans-meta}-vinylbenzyl (MVB), generated in a supersonically cooled discharge of \textit{m}-vinyltoluene, have been ...

Calcium monohydride CaH is found in the Sun and other stars. Indeed, its A-X electronic spectrum has been a useful probe for stellar classification.\footnote{For example, J.E. Gizis, \textit{Astron. J.} \underline{\textbf{113}}, ...

First high-resolution mid infrared rovibrational spectral data on jet cooled bromocarbene (HCBr) diradical are obtained using quantum shot noise limited laser absorption methods. The HCBr diradical is generated by coflowing ...

The addition reactions of iodine atom with propene in solid para-hydrogen (p-H$_{2}$) matrices were investigated with infrared (IR) absorption spectroscopy. Mixtures of propene and I$_{2}$ seeded in p-H$_{2}$ were co-deposited ...

Glycolaldehyde (HOCH$_2$CHO) has been detected in the interstellar medium; it is considered to play an important role in the formation of complex organic molecules, especially higher sugars. We took the advantages of unique ...

We are currently studying the $\tilde{B}$ $^2E'$ -- $\tilde{X}$ $^2A_2'$ system of jet cooled NO$_3$ via laser induced fluorescence (~LIF~) spectroscopy. The dispersed fluorescence (~DF~) spectrum from the vibrationless ...
