✦ Synopsis
Abstract
Carbon‐13 NMR chemical shifts are reported for nine tricyclic aromatic ketones formally derived from indanone. The influences of remote ring size, as well as linear, angular exo and angular endo ketone orientation are examined. Results are compared with available ^1^H NMR data. For indanone itself, based on selective ^1^H decoupling experiments, a recently reported CIDNP derived ^13^C signal assignment is shown to be in error.
