Optical Spectroscopy of Long Polyenes

We have synthesized a homologous series of soluble, linearly conjugated oligomers and related polymers using molybdenum alkylidene catalysts. We have developed HPLC procedures to isolate the oligomers according to their chain lengths and have obtained the absorption spectra of the purified oligomers in room temperature solutions and in 77 K glasses. The oligomer absorption spectra are structure...

Comment on "Effective field parameters in iron Mössbauer spectroscopy" [J. Chem. Phys. 47, 961 (1967)].

While the Mössbauer spectrum of a magnetically ordered powder sample can be used to determine the direction of the local hyperfine field (Bhf) in the coordinate system defined by the electric field gradient (efg) tensor, the spectrum of an oriented single-crystal provides a direct measurement of the angle between the absorbed or emitted γ and Bhf, primarily through the observed line intensities...

High Resolution Optical Spectroscopy

This experiment will allow you to learn a specific optical technique with applications over a wide variety of phenomena. You will use a commercial spectrometer (a very common piece of equipment in research labs) to obtain the emission wavelengths of particular elements (e.g. mercury, sodium, hydrogen and deuterium) as well as to compare the outputs of gas and solid state lasers. You will be abl...
