1. This is also a doppler-shift technique, but more precise than optical spectroscopy . 2. As an academic, his primary research interests include photonics and optical spectroscopy . 3. And famous for his book from 1995 entitled Principles of Nonlinear Optical Spectroscopy . 4. Golay worked on many problems, including gas chromatography and optical spectroscopy . 5. The two versions behave alike and are indistinguishable via optical spectroscopy . 6. Optical spectroscopy is further divided into atomic absorption spectroscopy and atomic emission spectroscopy.7. These effects are not limited to laser systems, or even to optical spectroscopy . 8. He has contributed to the theory of nonlinear optical spectroscopy . 9. Optical spectroscopy is a powerful technique to characterize charge-transfer bands.10. She also develops nonlinear optical spectroscopy and microscopy instruments for the examination of interfacial surfaces.
