This paper presents data on the bioactive phytoconstituents in analyzed using quantitative and qualitative phytochemical screening methods, Fourier Transform Infrared Spectroscopy and Gas Chromatography-Mass Spectrometry (GC-MS). Extracts were prepared in water, ethanol (EtOH) and EtOH:water mix. Identification of bioactive components was based on their spectral data and retention times compared with National Institute of Standards and Technology (NIST) mass spectral library. The most prominent absorption bands indicated are O-H stretching vibration, C-H stretch of polyols, aromatic C=C stretching vibration, O-H stretch of polyols, C-H stretching vibration and C-OH polyols. The GC-MS characterization for showed the presence of phenols, organic acids and carbohydrates with cannabidiol as the most abundant. Crude extracts of showed six phenolic compounds with 4-hydroxy-bezoic acid and cannabidiol present prominently. Six phenolic phytoconstituents were identified in extracts with 1,2,3-benzenetriol as the major polyphenolic compound. Biogenic iron oxide nanoparticles were synthesized and the formation was confirmed using a UV spectrometer (UV-3000 ORI, Germany) between 200 and 800 nm spectral range. X-ray diffraction (XRD) characterization of the biosynthesized iron oxide nanoparticles was carried out using Empyrean, Malvern PanAnalytical.

The magnetic material Nd2Fe14B is one of the strongest magnetic materials found in nature. The demand for the production of these nanoparticles is significantly high due to their exceptional properties. The aim of the present study is to synthesize magnetic nanoparticles of Nd2Fe14B using ethanol in the wet ball milling technique (WBMT).

Two-dimensional (2D) vibrational spectroscopy is a powerful means of investigating the structure and dynamics of complex molecules in condensed phases. However, even in theory, analysis of 2D spectra resulting from complex inter- and intra-molecular motions using only molecular dynamics methods is not easy. This is because molecular motions comprise complex multiple modes and peaks broaden and overlap owing to various relaxation processes and inhomogeneous broadening.

To consistently determine the anomalous characteristics of phthalic acid crystal (PAC) derivatives, we performed quantum dynamics simulations of the infrared spectral density of the h-PAC and d-PAC isotopomers that show up in the H/D isotopic frequency domain at two different temperatures viz. 77 and 298 K. A theoretical framework explaining the dynamical cooperative interactions within the hydrogen bonds (HBs) in the PAC crystals across a simulation of IR spectral density of the stretching band was developed.

: Increasing exercise intensity and performance output with superimposed vibration gains interest, especially in high-performance training. However, the additional benefit of vibration in passive stretching exercises and its mechanisms remain unclarified. : Passive stretching with (ST+V) and without (ST) vibration (20 Hz) was performed in male Olympic youth skiing athletes ( = 8, age: 17.

Elucidation of the vibrational relaxation process of interfacial water is indispensable for understanding energy dissipation at the aqueous interface. In this study, the vibrational relaxation dynamics of the hydrogen-bonded OH (HB OH) stretch vibration was investigated at the air/isotopically diluted water (HOD-DO) interface by time-resolved heterodyne-detected vibrational sum frequency generation (TR-HD-VSFG) spectroscopy. We observed the temporal change of the excited-state band ( = 1 → 2 transition), which enables a reliable determination of the time of interfacial water.
