- Why is this in E configuration? Im having problems seeing which group is higher or lower to properly assign E or Z.which one is the most suitable spectrum? (based on image) a/b/c/d/eThe absorbance of sample A is higher than the absorbance of sample B. Therefore, sample A has (circle the correct one) more / less dissolved solute than sample B. The absorbance is (circle the correct one) directly / inversely related to the transmittance of a sample.
