Magnetically Induced Circular Polarization of Emission: Application to Inorganic Complexes
A sensitive spectrometer for the measurement of circular polarization of emission, utilizing a photoelastic modulator, is presented. This spectrometer, when augmented by a superconducting magnet and dewar assembly, provides ...
A Scanning Tunneling Microscope with a Wide Sampling Range
Construction of a simple scanning tunneling microscope (STM) is described. This STM is suitable for atmospheric, controlled atmosphere, and high vacuum (but not UHV) work. This STM is especially wen suited for determining ...
An All Digital Inelastic Electron Tunneling Spectrometer Utilizing the IEEE-488 Instrument Bus and an IBM PC-XT Controller
An easily assembled computer‐controlled tunneling spectrometer is described. Spectral acquisition time is user selectable over a wide range. Low‐resolution spectra may be taken rapidly (about 30s/scan) or very slow scans ...
Phonon Scattering Times in a Molecular Crystal Below 10K Determined by Optically Detected Acoustic Paramagnetic Resonance
A combination of optically detected magnetic and acoustical paramagnetic resonance has been used to determine the phonon scattering time of microwave-frequency phonons in a molecular crystal in the 2- to 7-K temperature ...
Constant Resolution Tunneling Spectroscopy
An inelastic electron tunneling spectrometer is described which is capable of providing constantresolution spectra over the 0 to greater than 16 OOO-cm --I range. Constant-resolution data acquisition is especially beneficial ...
