Phase analysis of vibrational wavepackets in the ground and the excited states in polydiacetylene

Not Accessible

Your library or personal account may give you access

Abstract

Wavepackets of C–C and C=C stretching modes in the ground state start to oscillate π-out-of-phase with C≡C stretching mode. All the three modes in the self-trapped states observed indicate an acetylene-like structure not a butatriene-like.
