NOTES AND COMMENT 343 DETERMINATION OF CHLOROPHYLL AND PHEO-PIGMENTS : SPECTROPHOTOMETRIC EQUATIONS~ It has been shown that chlorophyll degradation products may at times constitute a significant fraction of the total green pigments present in seawater (Yentsch and Menzel 1963; Lorenzen 1965; Yentsch 1965). These degraded forms‚ or inactive chlorophyll‚ absorb light in the red part of the spectrum; if they are present in concentrations significant relative to chlorophyll a‚ a serious error

Thermochromism Thermochromism refers to the phenomenon of color changes by the agency of heat. Obviously‚ the color changes are made possible by the temperature-induced chemical or physical changes of materials incorporated into the inks. Sometimes‚ the color change occurring at a temperature is permanent‚ and at other times the original color can be regained on cooling. Accordingly‚ we have an irreversible or reversible thermochromic system. The required chemistry can be adopted based
