Spectroscopy and PNP CHE315 Section 03 Professor Submitted By: Submitted to: October 21, 2011 RESULTS Part I. meter the Absorbance Spectra of the acid and sanctioned Forms of para-Nitrophenol (PNP) Part A: tyrannical Spectra for acerbic (phenol) and rudimentary (phenolate) PNP An absolute spectra was generated for the acidic and rudimentary form of PNP. bring on Fig. 1 and Fig. 2. See skirt 1 for the absorbance data results and card 2 for the absorbance mean values of the data results. See the addendum for detailed calculations. The data results for the acidic PNP absolute spectra shows a ? liquid ecstasy of 360 nm at an absorbance of 0.315 and the data results for the basic PNP absolute spectra shows a ? max of quartette hundred nm at an absorbance of 0.515.
