Action spectroscopy of SrCl$^+$ using an integrated ion trap time-of-flight mass spectrometer
, 2014 The photodissociation cross-section of SrCl$^+$ is measured in the spectral range of 36000 -- 46000 cm$^{-1}$ using a modular time-of-flight mass spectrometer (TOF-MS). By irradiating a sample of trapped SrCl$^+$ molecular ions with a pulsed dye laser, X$

Enhancing Lipidomics With High‐Resolution Ion Mobility‐Mass Spectrometry
PROTEOMICS, EarlyView.ABSTRACT Lipids, indispensable yet structurally intricate biomolecules, serve as critical regulators of cellular function and disease progression. Conventional lipidomics, constrained by limited resolution for isomeric and low‐abundance species, has been transformed by ion mobility‐mass spectrometry (IM‐MS).

Prediction of forbidden ultraviolet and visible emissions in comet 67P/Churyumov-Gerasimenko
, 2015 Remote observation of spectroscopic emissions is a potential tool for the identification and quantification of various species in comets. CO Cameron band (to trace \cod) and atomic oxygen emissions (to trace H$_2$O and/or CO$_2$, CO) have been used to ...

The chemistry of interstellar molecules containing the halogen elements [PDF]
, 2009 Although they are only minor constituents of the interstellar medium, halogen-containing molecules are of special interest because of their unique thermochemistry. Here, we present a theoretical study of the chemistry of interstellar molecules containing

Rapid Communications in Mass Spectrometry, EarlyView.ABSTRACT Rationale Poly (acrylates)s can be distinguished from one another by the nature of their side chains. From model poly (acrylates)s, the purpose of this work was to evaluate the contribution of alternative activation techniques to the collisional activation, based on ion–ion and ion–photon interactions.

Spectroscopic analysis of bacterial photoreactivation
Photochemistry and Photobiology, Volume 101, Issue 2, Page 494-504, March/April 2025.This study investigates the effectiveness of fluorescence and Raman spectroscopy in detecting bacterial photoreactivation. Fluorescence spectroscopy shows limitations, because the intense fluorescence of tryptophan and tyrosine masks fluorescence emitted by thymine molecules.
