Experimental study of the gas phase chemistry of C3H3+ with several cyclic molecules

▶ Of the two isomers of C3H3+ the linear form is usually more reactive than the cyclic form. ▶ In reactions with nitrogen heterocyclic molecules both isomers are equally reactive. ▶ In reactions with oxygen heterocyclic molecules c-C3H3+ is more reactive though c-C3H3+ does react slowly.
