Raman SpectroscopySurface-enhanced Raman scattering (SERS) was discovered in the mid-1970s, by which the intrinsically low detection sensitivity of Raman spectroscopy is no longer a fatal disadvantage for this analytical tool. As a general introduction of SERS, the almost 40-year history of SERS ...
Infra‐red and Raman spectroscopies are highly chemically specific and nonヾestructive measurement tools that are widely used in pharmaceutical and biomedical analysis. In this chapter, the theory and some applications of infra‐red and Raman spectroscopies will be introduced. The chapter begins with ...
For Raman applications where the combination of resolution and sensitivity is required, we commonly recommend our AvaSpec-HERO with thermoelectrical cooling.To further enhance photometric sensitivity, we recommend using a detector collection lens (DCL-UV/VIS or DCL-UV/VIS-200), which is a ...
There are many spectroscopy classifications and different technical paths, including Fourier transform spectroscopy, Raman spectroscopy, fluorescence spectroscopy, terahertz, spectrometer and so on. 2. Spectral imaging technology The light source emits light of various frequencies (different wavelengths), which...
This statement is the opening remark from the Proceedings of the Symposium on Submillimeter Waves, which was one in a continuing series of meetings held at the Polytechnic Institute of Brooklyn since the early 1950s. That volume covers a diverse array of
The terahertz (THz) spectral region, in this book considered as the range from 0.3 to 10 THz (1 mm–30 μm), is one of the most exciting and, at the same time, most frustrating sectors of the electromagnetic spectrum. Exciting because of the wealth of knowledge that can be gained from...
Long-range Ising interactions (with a tunable power-law exponent ranging from α=0 to 3) are generated by stimulated Raman transitions, whereas the disorder in the form of a random transverse field can be ‘programmed’ experimentally using ac Stark shifts. With this setup, Ref. [87] finds ...
However, the observation of these structural changes by conventional spectroscopic techniques is limited, including the use of Raman and infrared spectroscopy. Chiroptical spectroscopy is sensitive to any structural changes to chiral molecules, so it can be used to sense any small structural changes. ...
5 now in its third edition, this classic text covers many aspects of infrared and raman spectroscopy that are critical to the chemist doing structural or compositional analysis. this work includes practical and theoretical approaches to spectral interpretation as well as a discussion of experimental ...
