摘要: The use of recently determined highly precise rotational constants for various isotopes formaldehyde and ethylene enables the ground-state average structures to be high accuracy. Harmonic corrections inertial are calculated using general harmonic force fields. In case formaldehyde, data enable changes in all three structural parameters due isotopic mass effects determined. For ethylene, only change CH bond length on deuteration is well characterized, somewhat lower accuracy constants. Using differences transferred from supported by calculations, deutero predicted what considered better than 0·1 per cent reliability. less formaldehyde. This although it appears also that stretc...
