Photodissociation Spectroscopy of [PDF]

Laser Chemistry, 1994
The photodissociation spectrum of is obtained from the yields of fragment ion as a function of photodissociation wavelength in the 400–1400 nm region. Two bands at 440 and 580 nm are attributed to the C ← X and the B ← X local excitation (LE) bands, respectively.

Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Temperature-dependent, rovibrationally resolved UV photodissociation cross sections of CH including multichannel nonadiabatic interactions

Astronomy & Astrophysics
Aims. The CH radical is ubiquitous across UV-irradiated astronomical environments, and its photodissociation represents one of the principal destruction pathways in regions exposed to ultraviolet radiation.

Recent Advances in Top‐Down Proteomics for Single‐Cell Research

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Individual cells have distinctive molecular characteristics, including biologically relevant proteoforms. Although single‐cell (SC) molecular omics offer unprecedented insights into cellular heterogeneity and function, the characterization of proteoforms in SCs remains an uncharted territory.
