Results Part I: Determining Absorbance Spectras of unpleasantic and basic Forms of PNP In Table 2, average out absorbency yarn of the acrid sheath of PNP continually decreased as the wavelength (nm) increased at an juristic separation of 10nm from 330nm to viosterolnm. Table 1: Absorbency data for acidic type at different wavelengths (nm) Wavelength(nm)| Absorbencyaverage| 330| 0.1570| 340| 0.1187| 350| 0.0763| 360| 0.0367| 370| 0.0090| 380| 0.0000| 390| 0.0000| four hundred| 0.0000| 410| 0.0000| 420| 0.0000| 430| 0.0000| 440| 0.0000| 450| 0.0000| 460| 0.0000| 470| 0.0000| 480| 0.0000| 490| 0.0000| 500| 0.0000| Figure 1 shows the absorbency of the acidic PNP sample gradually decreasing as the wavelength increases when measurable by using the spectrophotometer. Data from Table 1 was apply to fabricate the spectra to show the relationship and determine the lambdamax (?max). The ?max was set(p) to be at wavelength 330nm rea ding an absorbency of 0.1570. Figure 1: Absorbency of Acid Sample. With a spectrophotometer an acidic sample, mixture of 1ml 0.1µM PNP and 3mL ethanoate pilot film (pH 4.96), was prey at wavelengths from 330nm to 500nm at 10nm increments. Baseline reference use was acetate buffer of (pH 4.96).

In Table 2 the average absorbency reading of basic PNP sample increased, hit a note and past decreased as the wavelength continually increased from 330nm to 500nm of 10nm increments.
