A new radiation

Raman spectroscopy for fluid inclusion analysis

“…Monochromatic light scattered by matter contains radiations with frequencies different from the exciting light. This effect, predicted by Smekal (1923), was demonstrated by Raman (1928), and named after him. The discovery of a new optical scattering phenomenon won him the Nobel prize in physics in 1930.…”

Near-Infrared Multichannel Raman Spectroscopy with a 1064 nm Excitation Wavelength for Ex Vivo Diagnosis of Gastric Cancer

“…Individual bands in the Raman spectrum are characteristic for specific molecular motions because the energy level is unique to each molecule [9]. RAS is especially suitable for in vivo measurements because the power of the excitation light does not affect the tissue and the penetration depth is relatively large [10]. In our previous study, we utilized near-infrared RAS that had an excitation wavelength of 1064 nm [8].…”

“…The concept of RAS was originally established by Raman, C. V., in 1928 [9,10]. The technique detects Raman scattering, which represents inelastic scattered light that has undergone a small shift in wavelength called the Raman shift.…”

Degree of conversion of three composite materials employed in the adhesive cementation of indirect restorations: A micro-Raman analysis

“…[30][31][32][33][34][35][36][37][38][39][40][41][42][43][44] A precise method for assessing the DC of cement is Raman spectroscopy, [45][46][47] which allows for detailed measurement of the non-reacted methacrylate groups.…”
