WebWavelength vs. Absorbance of different pHs. I did an experiment where I compared buffer solutions at different pH levels. I used bromothymol blue as the pH indicator. I placed these solutions in a spectrophotometer and received the following data. Why does the maximum absorbance occur at the same wavelength (600 nm) for pH 11, 8, and 7 and 450 ... WebThe maximum absorption is moving to longer wavelengths as the amount of delocalization increases. Therefore maximum absorption is moving to shorter frequencies as the amount of delocalization increases. Therefore … WebThe conjugated pi system in 4-methyl-3-penten-2-one gives rise to a strong UV absorbance at 236 nm due to a π – π* transition. However, this molecule also absorbs at 314 nm. This second absorbance is due to the transition of a non-bonding (lone pair) electron on the oxygen up to a π* antibonding MO: This is referred to as an n – π* … college behind bars netflix
