The studies revealed that these two merocyanines exist in solutions as nonpolar (quinoid, i.e. vinylogous amide, ) or polar (zwitterionic, i.e. betaine, ) forms in their ground state, respectively. The dye with a nitro substituent can also form a hydrogen-bonded betaine (). This dye is...
Experimentalists have also studied, (15N2O)2,11,14,17 (15N14NO)2,5 14N2O-15N2O,13,14 and 15N14NO-15N2O.14 For all of these isotopologues they have determined rotational constants for the ground vibrational state of the polar and/or nonpolar forms. Rotational constants for the torsion, ...
Materials and growth issues for high-performance nonpolar and semipolar light-emitting devices Growth of InGaN/GaN light-emitting devices on nonpolar or semipolar planes offers a viable approach to reducing or eliminating the issues associated with p... RM Farrell,EC Young,F Wu,... - 《Semicond...
The present invention also provides a NO2sensor and a UV sensor, each of which uses the wire-type supercapacitor. The NO2sensor can stably detect NO2gas on fabric for a long time. The UV sensor can be attached to fabric to detect UV in color or quantitatively photocurrent. The present i...
ΔGsolvation represents the solvation energy given by the sum of the polar contribution (ΔGPB/GB) and nonpolar contribution (ΔGSA). ΔGPB/GB can be obtained using the Poisson–Boltzmann or generalized-Born models, while ΔGSA can be calculated by solvent accessible surface area (SASA). ...
Determine the number of valence electrons, give the overall shape of the molecule, and indicate whether the molecule is polar or nonpolar. Draw the Lewis structure with a formal charge XeF_4. Draw the ...
Although this method was developed for the determination of micromolar quantities of nitro-尾-hydroperoxides in lipid samples, it can be used to determine any long chain, nonpolar nitro compound. The method also can be adapted to allow the determination of polar or short chain nitro compounds by...
Ultraviolet spectra of a number of 2(2-hydroxyphenyl)2H-benzotriazoles were studied in nonpolar, polar, and hydrogen bonding solvents. The effect of substituents located in the 4-position of the benzo-triazole ring was investigated, and the effect on the UV absorption characteristics of 2(2-...
