Propyne (C₃H₄) is an isomer of cyclopropene with the structure H₃CCCH with one triple bond and a single CC bond (Szmytkowski and Kwitnewski, 2002). Its ground-state electronic configuration is given by Nakano et al. (2002) The geometric length of C₃H₄ molecule is approximately 0.484 nm and the width is ∼0.18 nm (Nakano et al., 2002). It has a dipole moment of 0.78 D and a quadrupole moment of 6.1 × 10⁻¹⁰ D m. It has 10 fundamental vibrational ...
