Хороший выход соединения получен из семян Alpinia nigra. Экспериментально найденные методами ИК и КР-спектроскопии колебательные моды подтверждены теоретическими расчетами с помощью теории функционала плотности (DFT) с использованием программного пакета Gaussian 09. Наночастицы Cu использованы для усиления слабых сигналов. В спектрах SERS усиление интенсивности (до 103 раз) наблюдалось для мод с более низкими частотами, соответствующих плоскостным деформациям. Это указывает на перпендикулярную ориентацию соединения относительно поверхности металла. Однако некоторые полосы ослаблены близостью поверхности металла. Оценка по ИК спектрам и с помощью электронной микроскопии показала, что наночастицы Cu находятся вблизи соединения.</p></abstract><trans-abstract xml:lang="en"><p>The vibrational characteristics of a labdane diterpene, (E)-labda-8(17),12-diene-15,16-dial, have been studied using FT-IR, FT-Raman and surface-enhanced Raman spectroscopy (SERS). A good yield of the compound has been sourced and isolated from the seeds of Alpinia nigra. Experimentally obtained vibrational modes of the compound obtained by IR and Raman were verified by theoretical calculations at density functional theory (DFT) level using Gaussian 09 software package. Copper nanoparticles have been used to enhance the inherently weak Raman signals of the compound. In the SERS spectra, intense enhancement (up to 103 fold) was observed in the bands at lower wavenumbers, corresponding to the in-plane deformations, which indicated perpendicular orientation of the compound on the metal surface. However, some bands were weakened by the proximity of the metal surface. This interaction was assessed by IR and visualized by electron microscopy, revealing that Cu nanoparticles lie in the vicinity of the compound, which is responsible for the SERS phenomenon.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы меди</kwd><kwd>лабдановый дитерпен</kwd><kwd>спектроскопия поверхностно-усиленного комбинационного рассеяния света</kwd><kwd>инфракрасная спектроскопия с преобразованием Фурье</kwd><kwd>Cu nanoparticles</kwd><kwd>labdane diterpene</kwd><kwd>surface-enhanced Raman spectroscopy</kwd><kwd>Fourier transform infrared spectroscopy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">G.
