title: Rydberg States of SiCl.
abstract: A fluorescence spectrum, excited by the synchrotron radiation of Superaco in a microwave discharge through He + SiCl(4), leads to the observation of five new electronic states of SiCl, converging to the ground X(1)Sigma(+) state of the SiCl(+) ion. The (n s varsigma) and (n p pi) Rydberg series are extended respectively to n = 6 and n = 7. A new ionization limit is observed in absorption at 11.238 eV corresponding to the a(3)Pi electronic state of SiCl(+). Four new states are observed which converge to that limit.
