Ethylbenzene absorption spectrum

Figure 8. Comparison of ethylbenzene absorption spectrum in methanol (32 OMA accumulations) with published fluorescence spectrum in cyclohexane. Arrows indicate spectral region of difference.

Spectra of three diphenyl derivatives of paraffins have been compared with those of biphenyl and ethylbenzene m Figure 4.4. The spectrum of Ph— (CH2)n—Ph when n is equal to two or greater, is near] identical with the absorption of ethylbenzene. PhCH2CH3, in double concentration. The two... 

The NMR spectrum taken when the reaction was finished, indicates few absorptions in the regions where the CINDP phenomena had been observed. Gaschromatographic analysis of the reaction mixture indicated that ethylbenzene had been formed in low yields (less than 10%) and it is this product that must be held responsible for the observed CIDNP phenomena.

The IR spectrum of ethylbenzene. The absorptions in the 3100-2880 cm" region indicate that ethylbenzene has hydrogens bonded to both sp and sp carbons. The two sharp absorptions at 1610 and 1500 cm" indicate that the sp carbons are due to a benzene ring.
