DFT, FT-Raman and FT-IR investigations of 1-cyclobutylpiperazine

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2012
FT-IR and FT-Raman spectra of 1-cyclobutylpiperazine (1cbpp) have been experimentally reported in the region of 4000-10 cm(-1) and 4000-50 cm(-1), respectively. The optimized geometric parameters, conformational equilibria, normal mode frequencies and corresponding vibrational assignments of 1cbpp (C(8)H(16)N(2)) are theoretically examined by means of ...

FT-IR, FT-Raman and SERS spectra of Vitamin C

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006
FT-IR and FT-Raman spectra of Vitamin c have been recorded and analysed. SERS spectrum was recorded is silver colloid. The molecule is thought to adsorb with the lactone ring in a tilted side on orientation with respect to the silver surface.

From 1D-FTS to Imaging FTS in astronomy

Fourier Transform Spectroscopy and Hyperspectral Imaging and Sounding of the Environment, 2015
FT spectroscopy started successfully in astronomy almost 50 years by 1D-FT on planets and stars. Today, Imaging FTSs only remain in use, providing unique capabilities of integral wide-field spectroscopy on a variety of extended sources, from the visible to the submillimetric domain.

FT-INFRACRVENI I FT-RAMANOVI SPEKTRI BIOTINA

2003
Snimljeni su i analizirani FT-infracrveni i FT-Ramanovi spektri biotina, nekih drugih sastojaka multivitaminskih pripravaka, te nekog multivitaminskog pripravka u čvrstom stanj. Ispitana je mogućnost kvlitativne i/ili kvantitativne analize biotina u odabranom pripravku, kako u čvrstom stanju tako i u vodenoj otopini. Analiza biotina dopunjena je UV/VIS

Investigations of FT-IR, FT-Raman, FT-NMR spectra and quantum chemical computations of Esculetin molecule

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2013
In this work, we report a combined experimental and theoretical study on molecular structure, vibrational spectra and electronic properties of Esculetin (ESC). The FT-IR, FT-Raman and FT-NMR spectra have been recorded and analyzed. The molecular geometry, harmonic vibrational frequencies, chemical shifts, HOMO, LUMO energies and molecular electrostatic

Stanovení obsahu silic pomocí infračervené (FT-FT-NIR) spektroskopie

2022
The bachelor thesis is devoted to the use of caraway root as a spice in the literature part, then the caraway itself (Carum carvi L.), essential oils and selected methods for the determination of essential oil content are described. The experimental part of the thesis deals with the determination of purity, dry matter content and weight per thousand ...
