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$

CN and HCN in Dense Interstellar Clouds
, 2005 We present a theoretical investigation of CN and HCN molecule formation in dense interstellar clouds. We study the gas-phase CN and HCN production efficiencies from the outer photon-dominated regions (PDRs) into the opaque cosmic-ray dominated cores.

OH$^+$ emission from cometary knots in planetary nebulae [PDF]
, 2018 We model the molecular emission from cometary knots in planetary nebulae (PNe) using a combination of photoionization and photodissociation region (PDR) codes, for a range of central star properties and gas densities.

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.ABSTRACT Rationale Accurate identification of phospholipid molecular species remains a major challenge in shotgun lipidomics because conventional tandem mass spectrometry typically resolves only one structural moiety at a time. This structural ambiguity limits confident lipid biomarker discovery and biological interpretation.

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

Photodissociation and chemistry of N2 in the circumstellar envelope of carbon-rich AGB stars [PDF]
, 2014 Context. The envelopes of asymptotic giant branch (AGB) stars are irradiated externally by ultraviolet photons; hence, the chemistry is sensitive to the photodissociation of N2 and CO, which are major reservoirs of nitrogen and carbon, respectively.

Journal of Applied Polymer Science, Volume 143, Issue 7, February 15, 2026.The combination of a rigid monomer (IBOA) and a flexible monomer (2‐EHA) via free‐radical copolymerization yields amorphous poly(IBOA‐co‐2‐EHA) with a wide range of tunable mechanical properties. The image depicts how increasing the IBOA content shifts the material's behavior from that of an elastic elastomer (PEHA) to a rigid, brittle plastic (PIBOA),
