Abstract
The high-resolution carbon 1s photoelectron spectroscopy of propyne (HC triple bond CCH3) displays a spectrum in which the contributions from the three chemically inequivalent carbons are clearly resolved and marked by distinct vibrational structure. The experimental results with gas-phase acidities are combined with ab initio calculations to give insights into the effects of initial-state charge distribution and final-state charge redistribution on ionization energies and acidities.
