Coherent broadband continuous-wave terahertz spectroscopy on solid-state samples
Measuring the complex dielectric function ε(ω)= ε1 + iε2 of solidstate samples in the terahertz frequency range with high spectral resolution remains difficult. Using a continuous-wave terahertz spectrometer based on photomixing in the frequency range from 60GHz to 1.8 THz, we obtain the most precise data of ε(ω) reported to date for the well-studied example of α-lactose monohydrate. We are abl...

متن کاملHigh-resolution continuous-wave coherent anti-Stokes Raman spectroscopy in a supersonic jet.
We have obtained high-resolution cw coherent anti-Stokes Raman spectra of the nu(1) Q branch of methane in an underexpanded supersonic jet at temperatures as low as 31.5 K and pressures below 2 Torr.
متن کاملHigh-resolution heteronuclear correlation spectroscopy in solid state NMR of aligned samples.
A new two-dimensional scheme is proposed for accurate measurements of high-resolution chemical shifts and heteronuclear dipolar couplings in NMR of aligned samples. Both the (1)H chemical shifts and the (1)H-(15)N dipolar couplings are evolved in the indirect dimension while the (15)N chemical shifts are detected. This heteronuclear correlation (HETCOR) spectroscopy yields high-resolution (1)H ...
متن کاملHigh Resolution Waveguide Terahertz Time-Domain Spectroscopy
Terahertz time-domain spectroscopy accesses the frequency range between 100 GHz and 5 THz by using the coherent generation and detection based on femtosecond laser sources. On the way to obtain fingerprint absorption spectra of molecular solids, terahertz waveguides have proven to be a valuable tool to extend the results to narrow and high resolution linewidths of crystalline solids. We will di...
