Isotopically enhanced infrared spectroscopy : a novel method for examining secondary structure at specific sites in conformationally heterogeneous peptides. Optical properties of liquid carbon measured by femtosecond spectroscopy. Only in selected cases, and even then with little depth, are the more common technologies such as near-infrared or mid-infrared spectroscopies applied and expounded. Near infrared re-ectance spectroscopy for analysing undried silage. The second attribute on which optical spectroscopy differs from colposcopically directed biopsy is in the timing of receiving test results and treatment.
