Parokanishi kombinatsionii rushnoi

Parokanishi kombinatsionii rushnoi, effekti Ra­man, yak nav parokanishi rushnoiro az kristall, moe va gazho guyand, ki dar natijai on basomadi rushnoi tagyir meyobad. Hangomp parokanishi kombinasionii rushnoii monokhromatii basomadash v dar spektri rushnoii parokandashuda basomadhoi ilovagii v ± v,- paydo meshavand, ki in jo Sh sobitahoeand, ki moddai parokandakunandaro tav-sif medihand va ba basomadi rushnoii parokandashavanda v vobasta nestand. Buzurgihoi V,- basomadhoi kh us us ii lappishhoi molekulahoi moddahoi parokandakunanda meboshand, ki ba sohai infrasurkhi spektr, muvofiq meoyand.

Parokanishi kombinatsionii rushnoiro soli1928 olimoni soveti G. S. Lands­berg va L. I. Mandelshtam (dar kristallho) va fizikhoi hind Ch. V. Raman va K. S. Krishnan (dar moeho) kashf kardaand. On baroi tadqiqi sokhti molekulaho istifoda meshavad. Spektrhoi parokanishi kombinatsionii har yak payvasti khimiyavi ba darajae khosi hamin payvakhst (meboshad, ki baroi tahlili sifati va mikdorii boetimodi tarkibi omekhtaho (masalan, benzinho, omekhtahoi karbogidridho va digar mahsuloti korkardi khimiyavi) asosi ko­mil meboshand.
