Photodissociation of the OD radical at 226 and 243 nm [PDF]
, 2003 The photodissociation dynamics of state selected OD radicals has been examined at 243 and 226 nm using velocity map imaging to probe the angle–speed distributions of theD(2S) and O(3P2) products.

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$

Local Quadrupole Ellipticity as Predictor of Anion‐Affinity in Nanographenes
Journal of Computational Chemistry, Volume 47, Issue 13, 15 May 2026.Anion affinity in nanographenes arises from anion–π interactions in electron‐deficient regions and CH‐‐‐anion hydrogen bonds in electron‐rich domains. Quadrupole moments help describe these interactions but have limitations in polycyclic systems. A regression model based on local quadrupole ellipticity predicts binding energies, highlighting local ...

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 ...

Substituent Effects on Cyanine Dyes Vary with Position and Chain Length
Advanced Optical Materials, Volume 14, Issue 19, 22 May 2026.In cyanines, substituent effects vary as a function of substituent position and cyanine length. Electron‐donating‐ and ‐withdrawing groups at meso‐ and α‐positions of 4n+1/4n−1 long cyanines (n = 1, 2, 3…) cause opposing, hypsochromic and bathochromic shifts of the 1st UV–vis absorption bands.

Photoprocesses in protoplanetary disks
, 2006 Circumstellar disks are exposed to intense ultraviolet radiation from the young star. In the inner disks, the UV radiation can be enhanced by more than seven orders of magnitude compared with the average interstellar field, resulting in a physical and ...

Advanced Optical Materials, Volume 14, Issue 17, 8 May 2026.Degradation in blue MR‐TADF OLEDs originates from high triplet density caused by slow RISC. LDI‐TOF MS directly detects host‐ and emitter‐derived fragments, providing molecular insight into how triplet accumulation drives degradation in the emissive layer. ABSTRACT Blue organic light‐emitting diodes (OLEDs) employing multi‐resonance thermally activated

The Chemical Effects of Mutual Shielding in Photon Dominated Regions
, 2012 We investigate the importance of the shielding of chemical photorates by molecular hydrogen photodissociation lines and the carbon photoionization continuum deep within models of photon dominated regions. In particular, the photodissociation of N2 and CN
