Vibrational spectra and first order hyperpolarizability studies of dimethyl amino pyridinium 4-nitrophenolate 4-nitrophenol

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2011
Vibrational spectra of the organic nonlinear optical crystallized dimethyl amino pyridinium 4-nitrophenolate 4-nitrophenol have been recorded and analyzed. The spectral interpretation has been done based on the density functional theory using the standard B3LYP/LANL2DZ basis set. Total energy distribution is calculated using the scaled quantum mechanic

Degradation of 4-Nitrophenol, 2-Chloro-4-nitrophenol, and 2,4-Dinitrophenol by Rhodococcus imtechensis Strain RKJ300

Environmental Science & Technology, 2010
A bacterial strain Rhodococcus imtechensis RKJ300 (= MTCC 7085(T) = JCM 13270(T)) was isolated from pesticide-contaminated soil of Punjab by the enrichment technique on minimal medium containing 4-nitrophenol. Strain RKJ300 is capable of utilizing 4-nitrophenol, 2-chloro-4-nitrophenol, and 2,4-dinitrophenol as sole sources of carbon and energy.

Reduction of 4-nitrophenol catalyzed by nitroreductase

Chinese Chemical Letters, 2007
Abstract The reduction of 4-nitrophenol catalyzed by nitroreductase in the presence of NADH was investigated in this paper. 4-Amino-phenol and 4-hydroxylamino-phenol were found in the reductive products. The relationship between reaction time and the reductive ratio were studied.

Crystal growth and characterization of 4-dimethylamino pyridinium 4-nitrophenolate 4-nitrophenol (DMAPNP) for NLO applications

AIP Conference Proceedings, 2019
The optically transparent organic single crystals of 4-dimethylaminopyridinium 4-nitrophenolate 4-nitrophenol (DMAPNP) were grown by slow evaporation solution technique (SEST) using acetone as a solvent. The cell parameters of the grown crystal were identified by single crystal X-ray diffraction (SXRD) analysis.

L-Phenylalanine–4-nitrophenol (1/1)

Acta Crystallographica Section C Crystal Structure Communications, 2006
In the 1:1 adduct formed between L-phenylalanine and 4-nitrophenol [alternative IUPAC name: (2S)-2-ammonio-3-phenylpropanoate-4-nitrophenol (1/1)], C9H11NO2.C6H5NO3, the L-phenylalanine molecule is in the zwitterionic state. The overall structure is stabilized via strong hydrogen bonding between polar zones and van der Waals interactions between non ...
