A double chain benzene sulfonate, deuterated on the benzene ring, and adsorbed to alumina showed a single resonance at low coverage, while at full coverage a discrete powder pattern was overlapping a single resonance, indicating the formation of a liquid crystal-like molecular environment in the la...
IR and Raman spectra (organic substancesIn the presence of two‐photon absorption in benzene at 5268 , we observe coherent anti‐Stokes Raman scattering at 993 and 935 cm1. These energies correspond to symmetric ring breathing vibrations (a1gsymmetry) in the1A1gground, and1B2uexcited state of...
Each of the four carbon atoms in the square ring cyclobutadiene moiety of biphenylene has distorted sp2 hybrid orbitals and associated σ-bond angles of 120°, 90°, and 150°, as shown in Fig. 1(c). A number of higher polycyclics containing the biphenylene nuclei were prepared and...
It should be considered that through a hyper crosslink- ing reaction with the FDA to benzene molar ratio of 3, the three carbons of the six carbons which exist in the benzene ring will be incorporated into neighborhood benzene molecules by cross linker molecule. So, the three available carbon...
We thus reason that the well dispersion of C3N4 in PMoV2 solution gives rise to a molecular-level contact between them, for which the creation of phenol may be possible from the immediate attack of PMoV2 catalyst to the already activated benzene ring on C3N4 surface. Indeed, the present ...
The α-and β-peltatins (XXIX; R=H and Me, respectively) have their (displaced) benzenoid bands near 274 mμ, which at first sight seems remarkably low for a ring A oxygenated podophyllotoxin type. We might have predicted λmax 295–300 mμ for the peltatins, but, as Hartwell and Sc...

2a), the main peak at 284.8 eV was ascribed to graphite sp2 carbon, which was derived from the benzene ring; for comparison, g-C3N4 showed the main peak at 288.2 eV corresponding to the NCN sp2 carbon [47,48]. The N 1s XPS spectra (Fig. 2b) of the both two samples showed...
