WebFourier transform infrared (FTIR) spectroscopy has been used to explore the thermal unfolding of three helical, alanine-based peptides. Each of the peptides follows the general sequence Ac-(AAAX)nA-NH2 where X is either Lys+ or Arg+ and n = 3 or 4. These particular peptides were chosen because they contain varying amounts of 3(10)- and alpha-helix. WebApr 20, 2001 · Infrared spectrum of neutral aniline in argon matrix 3.1. Spectra and vibrational assignments In its S 0 ( 1 A 1) ground electronic state, aniline is known to exist in two equivalent non-planar conformers and the dihedral angle between the ring and the amino plane is closed to 40°±2 [9], [10].
