Results Part I: Determining Absorbance Spectras of pointic and canonical Forms of PNP In Table 2, fair(a) absorbency yarn of the acrid illustration of PNP continually decreased as the wavelength (nm) increased at an reasoned separation of 10nm from 330nm to viosterolnm. Table 1: Absorbency data for acidic example 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 heedful 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 located to be at wavelength 330nm r eading 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 (pH 4.96), was prey at wavelengths from 330nm to 500nm at 10nm increments. Baseline reference utilize was acetate buffer of (pH 4.96).

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