High-throughput approaches for producing approximate vibrational spectral data for
molecules of astrochemistry interest rely on harmonic frequency calculations using …

A methane line list for the HITEMP spectroscopic database, covering 0–13,400 cm− 1 (> 746
nm), is presented. To create this compilation, ab initio line lists of 12 CH 4 from Rey et al …

Accurate parameters of molecular hot-band transitions, ie, those starting from vibrationally
excited levels, are needed to accurately model high-temperature spectra in astrophysics and …

The paper describes methods and fast computational algorithm for building effective
Hamiltonians in molecular physics using perturbative approach. Separations of fast and …

Even if on-board mm-wave/THz heterodyne receivers have been developed to measure
greenhouse gases (GHGs) atmospheric profiles, rotational spectroscopy rests under …

We use a Fourier transform spectrometer based on a difference frequency generation optical
frequency comb to measure high-resolution, low-pressure, room-temperature spectra of …

A tubular furnace is combined with a diode laser spectrometer to record the high
temperature near infrared absorption spectrum of methane at a pressure of 80 Torr. The …

This work describes the theoretical basis and implementation of the measurement of
vibrational (T vib) and rotational (T rot) temperatures in CH 4 by fitting spontaneous Raman …

We report the current status of our calculated spectroscopic relational databases. They
contain line lists for specific molecules, that result from recently published spectroscopic …

Spectra of hot methane were recorded using a tube furnace and a high-resolution Fourier
transform spectrometer. We obtained experimental absorption spectra in the 1.85–1.11 μm …
