Making molecules dance by shooting at them with infrared light.
My latest paper is published with open access. The paper concerns the tert-butyl hydroperoxide OH-stretching band oscillator strengths in the fundamental and first four overtones. This will help us understand the energetics of the atmos. important org-peroxides

Oscillator strengths of the fundamental and overtone OH-stretching bands of tert-butyl hydroperoxide in gas phase
We have recorded gas-phase room-temperature absorption spectra of t-BuOOH in the OH-stretching regions, ΔvOH=1−5, using a combination of Fourier trans…

We have measured absorption spectra of isoprene, the second most emitted biogenic VOC, in the entire range of JWST. We can use this data to detect and quantify isoprene (and life?) on Earth and on exoplanets.

The paper is open access.
Absorption cross section of gas phase isoprene in the infrared-visible range
We have recorded the gas phase spectrum of isoprene at room temperature from the mid-infrared range and into the visible range (600 cm−1 to 17050 cm−1…
