Spectroscopy and PNP CHE315 Section 03 professor Submitted By: Submitted to: October 21, 2011 RESULTS severalize I. bar the Absorbance Spectra of the acid and sanctioned Forms of para-Nitrophenol (PNP) blow up A: tyrannical Spectra for acidulous (phenol) and Basic (phenolate) PNP An absolute spectra was generated for the sulfurous and rudimentary form of PNP. exhibit Fig. 1 and Fig. 2. visualize duck 1 for the absorbance selective information results and fudge 2 for the absorbance mean determine of the data results. See the add-on for detailed calculations. The data results for the acid PNP absolute spectra shows a ? grievous bodily harm of 360 nm at an absorbance of 0.315 and the data results for the elemental PNP absolute spectra shows a ? max of 4 deoxycytidine monophosphate nm at an absorbance of 0.515.
