Mass Spectrometry Reviews, EarlyView., 2023 Abstract Analysis of triacylglycerol (TG) and phospholipid sn‐positional isomers can be divided into two main categories: (a) direct separation by chromatography or other means such as ion mobility mass spectrometry and (b) quantification of regioisomer ratios by structurally informative fragment ions with mass spectrometric methods.

Photodissociation of interstellar ArH+ [PDF]
Astronomy & Astrophysics, 2014 Aims. Following the recent detection of 36ArH+ in the Crab nebula spectrum, we have computed the photodissociation rate of ArH+ in order to constrain the physical processes at work in this environment. Methods. Photodissociation cross sections of ArH+ are computed in an ab initio approach including explicit account of spin-orbit coupling. Results.

Iron monoxide photodissociation [PDF]
The Journal of Chemical Physics, 2005 The photodissociation of Fe56O was studied by means of the velocity map imaging technique. A molecular beam of iron atoms and iron monoxide molecules was created using an electrical discharge with an iron electrode in a supersonic expansion of molecular oxygen.

A Theoretical Study of Temperature-dependent Photodissociation Cross Sections and Rates for O2
The Astrophysical Journal Supplement Series, 2023 The photodissociation of O _2 is thought to play a vital role in blocking UV radiation in the Earth’s atmosphere and likely has great importance in characterizing exoplanetary atmospheres.

The Catalyzed Photodissociation of Water [PDF]
Catalysis Reviews, 1984 Abstract Chemical interactions between molecules in excited electronic, vibrational, or rotational states and surfaces is a new field of catalytic science. Until recently, catalysis of chemical reactions has only been considered for molecules in their thermodynamic ground states.
