Practically most extreme hydrogen molecules showed positive charge normally, while the limit of carbon and nitrogen particles gangs the negative charge which is shown in the SI Table S1. 4. Conclusions The target molecule 1-(phenyl (piperidin-1-yl) methyl) naphthalene-2-ol was synthesized and ...
Table 1 Characteristics of spectral bands Wavenumber/cm 1 Absorption peak location and assignment 1025 =CH bending vibration in-plane of benzene 1107 C-O-C symmetric stretching vibration 1271 C-O asymmetric stretching vibration 1435 C=C stretching vibration of benzene 1720 -C=O stretching...
43、me.A1.2.4 Fuel Contamination:A1.2.4.1 The possibility of fuel contamination may beindicated in diesel crankcase lubricants by measuring the peakat 810 cm-1. Spectral characteristics of diesel (Figs. A1.5 andA1.6) and other fuels noted in Table A1.1 have been found tovary. Work is curre...
It is evident from the table that the mobility shift (given as ∆R/Rf ± cnf ) obtained in the ACE analysis due to the metal ion–BSA interactions was comparable to the percent change in the α-helical structure of the protein as determined by FT-IR analysis. In both the techniques,...
For the PBL aquadest fruit extract, hydroxychavicol was identified as the primary compound, making up 81.89% of the extract with an SI of 93%. This suggests that the suggesting that the compound plays a crucial role in the effectiveness of the extract against MRSA. Table 3. GC-MS analysis...
As can be seen from Figures 2–4, and from Tables 1 and 2, the prediction of the DFT calculations for the vibrational wavenumbers are in good agreement with the experimental values and allow for a complete assignment of the vibrational modes, with almost one-to-one peak correspondence, ...
The extracts of different ratios of ethanol–water were evaluated based on their ability to inhibit the α-glucosidase enzyme, as presented in Table 1. The IC50 values of salak fruit extracts ranged from 15.94 to 271.46 µg/mL. The inhibition potential of 100%, 80%, and 60% ethanol–...
(C≡C and C≡N), with almost no peaks in the IR spectrum of the Gentiana sample. The 1600–2000 cm−1region is known as the double bond stretching region (C=C, C=N, and C=O). The peaks around 1736 cm−1represent the CO stretching vibration of the ester, and the peak at ...
The spectra were further analyzed in terms of convoluted peak functions to determine the basic vibrational modes that contribute to the FT-IR signal by using a best-fit peak fitting routine of Origin software (Version 9.0, OriginLab Corporation, Northampton, MA, USA), based on the Levenberg-Mar...
Two models, one based on spectral peak intensity at 1406 cm´1 and the other on the ratio of the peak intensity against intensity at a neutral band, were developed for evaluating metanil yellow concentration in turmeric powder. The first model evaluated the intensity of the metanil yellow ...
