 Abstract: Highly correlated ab initio calculations with large basis sets are reported for difluoroethyne, FCCF. Based on CCSD(T)/cc-pVQZ results, a reliable theoretical equilibrium geometry is derived:re(CC) = 1.1860(6) Å and re(CF) = 1.2835(4) Å. Correlated harmonic (CCSD(T)/cc-pVQZ) and anharmonic (MP2/TZ2Pf) force fields provide improved theoretical predictions for the fundamental vibrational wavenumbers and other spectroscopic constants.
