Design of a Novel Apparatus to Enrich Analytes via a Diffuse-Evaporation Process for HPLC-FTIR Analysis
HPLC-FTIR analysis using a novel apparatus with CuO powder as an interface is reported. This apparatus initially serves as a reservoir for the dilute eluted solution of HPLC, and then acts as an enrichment dev...

Using Lanthanum Fluoride Fine Particles as Stationary Phase for Thin-Layer Chromatography/Fourier Transform Infrared Spectroscopy Analysis
While in situ TLC/FTIR technique has tremendous potential in the analysis of complex mixtures, the conventional stationary phase, such as silica gel, used for TLC/FTIR analysis, has strong absorption in IR region...

Structural basis for the discrepancy of spectral behavior in C-H stretching band between steroids and long chain hydrocarbon compounds
The discrepancies of the spectral behavior for the C-H stretching band between some long chain hydrocarbon compounds and steroids were investigated. At low temperature, the C-H stretching bands exhibit complex...

Fractal phenomena in molecular mechanics calculation
It is proposed that in molecular mechanics calculation points belonging to various stable or meta-stable conformers are mixed up and form fractal structures in conformation space. The calculation results show ...

Infrared Spectroscopic Characterization of the Crystallinity and the Hydrocarbon Chain Packing of the Polyethylene Segments in Poly(ethylene-co-dimethylaminoethyl Methacrylate)
The multicrystalline behaviour and the crystallinity of poly(ethylene-co-dimethylaminoethyl methacrylate) were investigated by infrared spectroscopy. The metastable monoclinic packing structure of the polyethy...
