Abstract

Microwave studies of the structural and dynamical properties of several organic acids and their water complexes have been described by a number of research groups. Here we continue this theme by the study of valeric acid and 5-aminovaleric acid, using chirped-pulsed Fourier transform microwave spectroscopy (CP-FTMW). The rotational spectrum from 6.5 to 18 GHz was collected using a compilation of 250 MHz chirped pulses and pieced together. Their structures and water complexes were determined and will be compared to other amino acids.
