Hello and welcome to my homepage on this the

My name is Jeffrey Philippson and I am in the process of completing a Ph.D. in physics on the Trent-Queen's graduate program. I am an experimental physicist and my research has been carried out as part of the Optical Physics Group at Trent University in Peterborough, Ontario, Canada. I was born and raised in Manchester, UK, but have lived in Ontario since 2005. I successfully defended my doctoral thesis on January 20th, 2012 and shall be returning to the UK in early February.

I am currently on the lookout for a position as an industrial physicist in the UK in the fields of electronic/optoelectronic instrumentation, optics and spectroscopy, precision measurements and data analysis, or anything else that utilizes the broad skills-set I have obtained as an academic researcher in experimental physics. My résumé includes a detailed skills summary.

Angular momentum coupling in hydrogen fluoride

Featured Picture

The angular momentum coupling scheme for hydrogen-fluoride (HF).

The orbital angular momentum, L, is coupled to the internuclear axis via the electrostatic force while the electron spin, S is more weakly coupled via the spin-orbit interaction. The precise orientations of L and S are not well defined so the axial components, Λ and Σ respectively, are combined to form a vector, Ω, that is coupled to the rotational angular momentum, R, to form J. The nuclear angular momenta, IF and IH, are coupled in order of their contributions to the hyperfine energy to form first F1 and then F. See our publication for more details.
