Raman spektrometri

Raman spektrometri Raman sochilish effektiga asoslangan analitik asbob bo'lib, molekulyar tebranishlar, aylanishlar va moddalarning boshqa past chastotali rejimlarini o'rganish uchun ishlatiladi. Namuna lazer yorug'lik manbai bilan o'zaro ta'sirlashgandan so'ng sochilgan yorug'likning chastota siljishini tahlil qilish orqali Raman spektrometri namunaning molekulyar tuzilishi, kimyoviy tarkibi va fazaviy o'zgarishlari haqida ma'lumot berishi mumkin. U qattiq, suyuq va gaz namunalarini buzmasdan tahlil qilish uchun ishlatilishi mumkin, bu esa uni kimyoviy tahlil, materiallarni tadqiq qilish, farmatsevtika aniqlash, hayot fanlari va atrof-muhit monitoringi uchun ayniqsa mos qiladi. Raman spektrometrlari yuqori sezgirlik, tezkor tahlil va murakkab namunalarni tayyorlashni talab qilmaslik afzalligini taklif etadi, bu ularni molekulyar tuzilmalar va material xususiyatlarini o'rganish uchun kuchli vositaga aylantiradi.
