Abstract
The enthalpy of sublimation of C3 as determined by a second law method using both emission and absorption measurements agrees with total vapor pressure and mass spectrometer measurements. The enthalpy agreement and integrated absorption coefficient measurements demonstrate that the so‐called continuum of C3 is a pseudocontinuum and involves the same bound states as the discrete Swings bands of C3(A1Πu↔X1Σ g+). ΔH0°=188±5 kcal/mole for the sublimation of C3 yields an oscillator strength for the 4050 A bands of C3 of 0.13 within a factor of 2.Keywords
