Ilmiy tadqiqot yo‘nalishi:
Molekulyar klasterlarning hosil boʼlish mexanizmlari va ularning xossalarini tebranish spektrlari yordamida o‘rganish. Biologik obyektlarda nanoo’lchamli molekulyar klasterlarning spektroskopik parametrlarini aniqlash, tahlil qilish va bu ob‘etlardan amaliyotda foydalanish bo‘yicha tavsiyalar ishlab chiqish.
Ilmiy tadqiqotlarining asosiy natijalari:
Suyuq va kristall holatlardagi yuqori qutbli molekulalardan tashkil topgan moddalarda, 10 tagacha molekulaga ega boʼlgan klasterlarning shakllanish mexanizmlari aniqlangan va molekulyar klasterlar hosil boʼlish jarayonlarining murakkab tizimi asoslangan; yuqori qutbli moddalarning suyuq va izolyatsiyalangan holatlarda klaster tuzilishlarini hosil boʼlishida ichki molekulyar va molekulalararo vodorod bogʼlanish oʼrni hamda klasterlarning geometrik va elektrooptik parametrlari aniqlangan; molekulyar klasterlarda molekulalararo vodorod bogʼlanish hosil boʼlishida ishtirok etgan va ishtirok etmagan O-H tebranishlarga tegishli polosalarining yangi spektroskopik talqini taqdim qilingan; molekulyar klasterlar shakllanish jarayonida gaz holatdan suyuq holatga oʼtishida ikkita tebranish polosalar sistemasi hosil boʼlishi, bu polosalar "simmetrik" (past chastotali) va "antisimmetrik" (yuqori chastotali) O-H tebranishlar bilan bogʼliqligi koʼrsatilgan; suyuq suv tuzilishining shakllanishida beshta va oltita molekuladan tashkil topgan (yopiq zanjirli) molekulyar klasterlarning oʼrni eng yuqori ekanligi isbotlangan; molekulalararo vodorod bogʼlanishli molekulyar suyuqliklarning tuzilishi va fizik xossalari ulardagi tashkiliy tuzilma elementi sifatidagi nanooʼlchamli klasterlar mavjudligi bilan aniqlanishi isbotlangan.
