Fluorescence and Relaxation Dynamics of Cesium in Argon Matrices: Multiple Trapping Sites and Host-Guest Interactions
S. Lahs, H. Dinesan, S. Mahapatra +6
We investigate the fluorescence and relaxation dynamics of Cs atoms embedded in a cryogenic argon matrix using spectroscopy measurements combined with diatomic-in-molecule (DIM) si…
A fast and streamlined method for the measurement of absolute photodetachment and photodissociation cross-sections
Salvi Mohandas, Uma Namangalam, Abheek Roy +2
The absolute photodetachment cross-section characterizes the photostability of atomic and molecular anions against photodestruction by neutralization. The measurement of this quant…
Suppression of collision-induced dissociation in a supersonically expanding gas
Uma Namangalam, Salvi Mohandas, Hemanth Dinesan +1
In high-resolution mass spectrometry, an electrospray ionization source is often paired with an ion-funnel to enhance ion transmission. Although it is established that ions experie…
Laser-Induced Fluorescence Spectroscopy (LIFS) of Trapped Molecular Ions in Gas-phase
Hemanth Dinesan, S. Sunil Kumar
This review presents the Laser-Induced Fluorescence Spectroscopy (LIFS) of trapped gas-phase molecular ions. A brief description of the theory and experimental approaches involved…
Absorption line shape recovery beyond the detection bandwidth limit: application to the precision spectroscopic measurement of the Boltzmann constant
François Rohart, Sinda Mejri, Papa Lat Tabara Sow +8
A theoretical model of the influence of detection bandwidth properties on observed line shapes in laser absorption spectroscopy is described. The model predicts artificial frequenc…
