The infrared spectrum of 14 N 2 -CH 3 CCH in the 3.0-mm region has been observed and the rovibrational transitions have been assigned for the A (m Γ 0) and E (m Γ {1 ) methyl top internal rotor states of this near slipped parallel van der Waals molecule. The E-state transitions were used to estimate

β¦ Synopsis
van der Waals clusters exhibit spectroscopically distinct isomers for n = 2 and 4. The ionization potentials (IP)oftheseisomersdifferby33(n=2)and56cm-'(n=4),orabout25%ofthetotalIPshiffinducedbytheclu~ter.Based on this IP difference, isomer-selective ionization and electronic spectroscopy have been performed.
