摘要：
A full structural assignment of the most stable conformers of phenylalanine, based upon a combination of ultraviolet and infrared ion-dip spectroscopy of the jet-cooled amino acid, coupled with high-level ab initio computation is presented for the first time. The results are discussed in relation to aliphatic amino acids to highlight the importance of ring-side chain interactions; the question of zwitterion formation is also discussed.
