Abstract

Infrared spectra of gaseous and solid 2-cyclopropylpropene (2-CPP, c-C3H5C (CH3) CH2) have been recorded from 3500 to 40cm− 1, and Raman spectra (3200–150cm− 1) of the liquid as well as mid-infrared spectra of 2-CPP in liquid krypton solution (from− 105 to− 150° C) were also obtained. Ab initio calculations, with basis sets up to 6-311+ G (2df, 2pd), were carried out for this molecule, using the restricted Hartree–Fock (RHF) approach, with full ...
