摘要：

The C-13 and O-17 chemical shifts of a number of ketenes are reported and discussed in terms of electronic and mesomeric substituent influences. New deshielding alpha- and shielding gamma-heavy-atom effects are reported. The corresponding data for carboxylic acid bromides and chlorides are given.
