Experimental
We are Studying the unimolecular dissociation of 2,3-dihydrofuran (DHF). The molecule was dissociated in a potential field of 1000 V through Penning Ionization in Argon then expanded into a vacuum creating a super-sonic expansion.

We have characterized up to 14 distinct species in the product spectrum. These include formaldehyde, propyne and propene as lighter fragment species. More interestingly, we have identified several isomeric and conformational species of the starting product DHF. These include cis- and trans-cyclopropane carboxaldehyde (CPCA) and trans-crotonaldehyde (CA).
