At Sussex we created many new molecules and studied them by microwave spectroscopy and photoelectron spectroscopy

HCP C6H5CP

The first carbon phosphorus double C=P bonded species – phosphaalkenes

General method for creating carbon phosphorus triple bonded species – phosphaalkynes – only HCP previously known (for more than a decade)

General thermolytic routes to new unstable species - thiocarbonyls

ClB=S BrB=S

General method for creating Boron –Sulphides

General method for creating cyanopolyynes

I had a hole drilled though the base plate and filled it with Argon

Sussex NNC

We deposited soot from the carbon arc on an electron microscope slide and varied the

Argon pressure

Sussex NNC

Electron microscopy indicated that the structure of the deposited soot changed

dramatically as the pressure was raised to over 80 microns

A manuscript of a paper presented at a conference in Capri sent to me by

Mike Jura a professor of astrophysics at UCLA
