TLDR
In this paper, the rotational constants for the excited state are S ‘ = 1.8755, B ‘ 0.4042, C ‘= 0.3378 cm −1 by the plausible assumption that the important changes in the molecule are in the C=0 bond length, the OCO angle, and the nonplanarity due to the formyl hydrogen.About:

Some speculations on the mechanisms of photochemical vapor generation
TL;DR: In this article, a model based on the photochemical generation of free radicals involving ligand to metal charge transfer reductions and oxidations was proposed to account for the production of volatile metal species arising from photochemical vapor generation in acetic and formic acid media.

Photodissociation of formic acid
TL;DR: In this article, a time-resolved Fourier transform infrared spectrometer was used to detect the vibrationally excited nascent products of CO, CO2 and CO2(v) after laser photolysis at 248 or 193 nm.

Theoretical study of the electronic gas-phase spectrum of glycine, alanine, and related amines and carboxylic acids.
TL;DR: A theoretical study on the origin of the common electronic excitations in amino acids is presented, focusing on the excited states of glycine, alanine and the related substructures formic acid, acetic acid, propionic acid, ammonia, methylamine, and ethylamines.

(2+1) resonance‐enhanced multiphoton ionization–photoelectron spectroscopy of the OH radical
TL;DR: In this paper, a (2+1) resonanceenhanced multiphoton ionization-photoelectron spectroscopy (REMPI•PES) study of the OH radical has been carried out in the two-photon energy region between 81 300 and 88 900 cm−1.

TL;DR: It is shown by Coulomb explosion imaging that circularly polarized light can also induce a chiral fragmentation of a planar and thus achiral molecule, and might trigger new approaches to improve laser-driven enantioselective chemical synthesis.

Report on Notation for the Spectra of Polyatomic Molecules
TL;DR: A SATISFACTORY standardization of notation for diatomic molecules and their spectra already eXIsts. as mentioned in this paper has been proposed for the entire range of polyatomic spectroscopy from ultraviolet to microwave and magnetic resonanc spectra.

Electronic Spectra of Isoelectronic Amides, Acids and Acyl Fluorides
TL;DR: The first four bands in the gas-phase spectra of amides, carboxylic acids, and acyl fluorides are thought to be n'→'π*, n'↵'3s Rydberg, π → π*, and n´→'3p Rydinger excitations, whereas the first and third are valence shell.
