It is well known among spectroscopists that hydrogen has two modifications: para-H$_2$ and ortho-H$_2$. Pure para-H$_2$ can be produced by leading ``normal'' H$_2$, a 3:1 ortho:para mixture, over a catalyst at low temperature. ...

Two dimensional (2D) semiconductors and their artificial structures hold great promises for electronic, optoelectronic, and quantum devices. We developed a facile method to disassemble van der Waals (vdW) single crystals ...

After the first highly accurate IR intensity study on CO$_{2}$ 20012-00001 band was published in 2015, [Polyansky et al, PRL 114,243001 (2015)], reliable intensity data have been accumulated experimentally for several other ...

The alkaline earth monohalides are molecules of interest in fields such as astrophysics, high-temperature chemistry, chemiluminescent reactions, spectroscopy, computational chemistry, and cold molecule trapping. The ...

Accurate absorption models for gases at high pressure and temperature are needed for applications in both planetary and combustion science. Absorption models for these conditions require complete databases of temperature-dependent ...

Characterizing and modelling the atmospheric CO$_2$ with a sub-percent accuracy necessitates high-quality spectroscopic lineshape parameters. For this goal, we collected the best experimentally and theoretically measured ...

Multiply charged diatomic molecules are exotic gas-phase species and require high amounts of energy to be produced. Fundamental questions regarding the structures, stabilities, and bonding schemes of small multiply charged ...

The SMAUG apparatus (Spectroscopy of Molecules Accelerated in Uniform Gas flows) was developed to produce hot spectra of various molecules of interest for hot astrophysical atmospheres, like the one surrounding hot Jupiters, ...

Whereas the electronic ground states of a large number of small molecular cations have been spectroscopically characterized, much less is known concerning electronically excited states, in particular because of the low ...

Nitrous Oxide is the third largest contributor to the greenhouse effect having a potency 300 times that of \chem{CO_2}. Furthermore it is a metastable molecule that can be catalytically converted into harmless nitrogen and ...
