41. Oxidized flavins have high absorbances of about 450 nm, and fluoresce at about 515-520 nm. 42. Linner mentioned that most caramel colors had log absorbance spectra which were essentially linear in the visible range. 43. Absorbance of different concentrations of tyrosine reacted with Folin-Ciocalteu's reagent are detected at 660 nm44. Absorbance is measured using a microtiter plate reader, at 450 nm with a 650 nm reference filter.45. Formaldehyde is detected in air based on fungal growth inhibition, reflected by suppressed mycelium growth and absorbance . 46. When these two cancer-related cellular parameters are satisfied, a change is observed in the absorbance spectrum. 47. One system checks the decrease in absorbance at 340 mm when the ammonia reacts with alpha-ketoglutaric acid. 48. The "'hyperchromic effect "'is the striking increase in absorbance of DNA upon denaturation. 49. Where is the optical path length, is a molar absorbance at unit path length and is a concentration. 50. The scattering and absorbance cross-sections describe the intensity of a given frequency to be scattered or absorbed.
