The smglet electromc ground state of vmyhdene WIU be very dtfficult to observe spectroscopically, as It rapldly tunnels througfi a small (6 kcal mol-'1 barner to acetylene TrIplet vmyhdene should have a much longer hfetune, and several prelctlons of Its PropertIes are reported here These mclude the mfrared spectrum and a characterlzatton of the allowed 3Bz -

Pyrolysis (900 K) of cyclopenteno-1.2,3-thiadiazole with trapping of the products in argon at 20 K gave ethylene and propadienethione. Small quantities of thioketene and trimethylenethioketene were also formed. The infrared bands due to propadienethione were identified by their disappearance on irra
