A new method for measuring the dielectric and absorption constants of materials at millimeter frequencies is described. This new method is called digital spectrometry and rests on a little known property of Fresnel's equations for reflection at 45 deg and the recent appearance of highly accurate digital voltmeters. The fundamental equations for digital ...

Boron azadipyrromethenes are red-light-absorbing dyes with chromophoric capabilities deriving from a conjugated, chelating framework. Reported here are tricoordinate copper(I), silver(I), and gold(I) complexes of a tetraphenylazadipyrromethene ligand. The new complexes are characterized by optical absorption and emission spectroscopy, multinuclear NMR, mass ...

Thermal Lens Spectrometry has traditionally been carried out in the single-beam and the mode-mismatched dual-beam configurations. Recently, a much more sensitive dual-beam TL setup was developed, where the probe beam is expanded and collimated. This feature optimizes Thermal Lens (TL) signal and allows the use of thicker samples, further improving the ...
