✦ Synopsis

We describe the results of a number of experiments which demonstrate competition between three-photon resonance-enhanced multiphoton ionisation and third-harmonic generation (THG) at wavelengths near the (= 'IT.-% 'Z.$ (rc: 4so,+x:) Rydberg transition of acetylene. The results serve to strengthen a recent suggestion by Katz, Tsukiyama and Bersohn that THG will prove to be a general phenomenon for poly-atomic molecules with sharp Rydberg transitions.
