Abstract
The ab initio rotational constants of the isocyanopolyynes of formulae HC5N, HC7N, HC9N, and HC11N have been calculated. Their respective va lues are 1.3925, 0.5653, 0.3111, and 0.1869 GHz, respectively. Inaccur acies of just a few tenths of 1% may be expected. The recent discovery of isocyanopolyynes, and the presence of cyanopolyynes in different i nterstellar clouds allow one to think that the isocyanopolyynes studie d here may be detected in the near future.
