AB The rotational spectrum of the natural amino acid tryptophan has been observed for the first timeusing a combination of laser ablation, molecular beams, and Fourier transform microwave spectroscopy.Independent analysis of the rotational spectra of individual conformers has conducted toa definitive identification of two different conformers of tryptophan, with one of the observed conformersnever reported before. The analysis of the 14N nuclear quadrupole coupling constants is ofparticular significance since it allows discrimination between structures, thus providing structuralinformation on the orientation of the amino group. Both observed conformers are stabilized by anO–H · · ·N hydrogen bond in the side chain and a N–H · · · π interaction forming a chain that reinforcethe strength of hydrogen bonds through cooperative effects.
