Submillimeter Spectrum of Formic Acid

Submillimeter Spectrum of Formic Acid

We have measured new submillimeter-wave data around 600 GHz and around 1.1 THz for the C isotopologue of formic acid and for the two deuterium isotopomers; in each case for both the trans and cis rotamer. For cis-DCOOH and cis-HCOOD in particular only data up to 50 GHz was previously available. For all species the quality and quantity of molecular parameters has been increased providing new mea...

Treatment of Warts with Topical Formic Acid

The electronic spectrum of chloroformic acid in comparison to formic acid.

The electronic spectra of chloroformic acid ClCOOH and formic acid HCOOH are computed in large-scale multireference configuration interaction (MRD-CI) calculations. The computed spectrum of formic acid is in reasonable agreement with prior calculations and experimental data. The first electronic transition of ClCOOH is computed at 6.41 eV (193.4 nm), about 0.5 eV higher than in HCOOH. Together ...

Enzymic oxidation of formic acid.

Interest in the metabolic fate of formic acid has been renewed as the result of recent experiments showing active incorporation of carbon-labeled formate into normal body constituents of the pigeon (l-3) and the rat (4, 5). Prior to these findings, enzymes capable of catalyzing the oxidation of formic acid had been reported, widely distributed in plant and animal tissues (6). Only in the case o...
