The rotational spectra of two conformers of tryptamine have been assigned by free jet millimeter-wave absorption spectroscopy. Both of them are stabilized by an intramolecular N–H p bridge, formed between the amino group of the lateral chain in position 3 and the p system of the pyrrole unity. They correspond to the two most stable conformers found by resonant ion-dip infrared and UV–UV hole burning spectroscopies [J. R. Carney and T. S. Zwier, J. Phys. Chem, 2000, 104, 8677].

Abstract
The rotational spectra of two conformers of tryptamine have been assigned by free jet millimeter-wave absorption spectroscopy. Both of them are stabilized by an intramolecular N–H p bridge, formed between the amino group of the lateral chain in position 3 and the p system of the pyrrole unity. They correspond to the two most stable conformers found by resonant ion-dip infrared and UV–UV hole burning spectroscopies [J. R. Carney and T. S. Zwier, J. Phys. Chem, 2000, 104, 8677].File in questo prodotto:
