INFLUENCE OF MOLECULAR AND CRYSTAL STRUCTURE ON NONLINEAR OPTICAL PROPERTIES OF HYDRATED AND ANHYDROUS POTASSIUM L-2-NITRIMINO-1,3-DIAZEPANE-4-CARBOXYLATE CRYSTALS

Abstract

Физические свойства кристаллов зависят от их химического состава, молекулярной и кристаллической структуры. Присутствие донорных аминогрупп (NH 2 ) и акцепторных нитрогрупп (NO 2 ) в молекуле может повысить нелинейно-оптические (NLO) свойства молекулы. L- нитроаргинин в сильнощелочной среде (МЗ (М = Li, Na, K) кристаллизуется с образованием L – 2 – нитримино – 1,3 – диазепан – 4 – карбоновой кислоты ( L –NIDCA.H 2 O и L). -NIDCA). Мы обнаружили, что медленное испарение раствора L- нитроарганина и щелочи в эквимолярных количествах приводит к образованию соли металла с L–2 – нитримино – 1,3 – диазепан – 4 – карбоксилат-анионы (K ( L –NIDC) .H 2 O, Na ( L –NIDC), L –NaNIDC, Li ( L –NIDC); эта соль демонстрирует сильный NLO В этом исследовании также рассматривались вопросы генерации кристаллов L –KNIDC.H 2 O и L –KNIDC во второй гармонике и влияние их кристаллической и молекулярной структуры на свойства NLO. Инфракрасный и комбинационный спектры K ( L –NIDC) .H Кристаллы 2 O и K ( L –NIDC) были изучены с учетом этих структурных особенностей. Мы обнаружили, что интенсивность генерации второй гармоники в K ( L–NIDC) в 2,75 раза выше, чем в стандартном кристалле KDP, а интенсивность в K ( L –NIDC) .H 2 O значительно ниже.
