The inverse Raman effect is a form of Raman scattering first noted by W. J. Jones and Boris P. Stoicheff. In some circumstances, Stokes scattering can exceed anti-Stokes scattering; in these cases the continuum (on leaving the material) is observed to have an absorption line (a dip in intensity) at ν L +ν M.
Meta analysis by authors Ray, Bratton, Rhine and Jones, 2001, found an even larger effect size for nondirective play therapy, with children performing at 0.93 standard deviations better than non-treatment groups. [29] These results are stronger than previous meta-analytic results, which reported effect sizes of 0.71, [55] 0.71, [56] and 0.66. [36]
Although the inelastic scattering of light was predicted by Adolf Smekal in 1923, [3] it was not observed in practice until 1928. The Raman effect was named after one of its discoverers, the Indian scientist C. V. Raman, who observed the effect in organic liquids in 1928 together with K. S. Krishnan, and independently by Grigory Landsberg and Leonid Mandelstam in inorganic crystals. [1]
Sensory integration therapy (SIT) was originally developed by occupational therapist A. Jean Ayres in the 1970s to help children with sensory-processing difficulties. It was specifically designed to treat Sensory Processing Disorder (sometimes called Sensory Integrative Dysfunction). [ 1 ]
Art therapy can be implemented as a holistic therapeutic practice for child cancer patients as well (effecting 1 in 285 children in the US; 15,980 children each year). [16] Given the alleviating effects that are addressed by this method, children were better able to discuss their needs and emotions to their family members and healthcare team.
A Raman laser is a specific type of laser in which the fundamental light-amplification mechanism is stimulated Raman scattering. In contrast, most "conventional" lasers (such as the ruby laser ) rely on stimulated electronic transitions to amplify light.
Adolf Gustav Stephan Smekal (12 September 1895 – 7 March 1959) was an Austrian theoretical physicist, with interests in solid state physics, [1] known for the prediction of the inelastic scattering of photons (the Raman effect).
Raman optical activity (ROA) is a vibrational spectroscopic technique that is reliant on the difference in intensity of Raman scattered right and left circularly polarised light due to molecular chirality.
