Description

General description

Formic acid is the simplest carboxylic acid. Crystal structure study by single-crystal X-ray diffraction technique at -50°C has shown that it has an orthorhombic structure with space group Pna. The photodegradation of formic acid has been investigated using ab intio calculations and time-resolved Fourier transform infrared spectroscopy. Its utility as a fuel in direct fuel cells has been studied. The momentum distribution for its monomer have been evaluated by electron momentum spectroscopy (EMS).
