III. Contributions to the chemistry of chlorophyll. Part I

Abstract

The paper treats of the products formed by the action of acids on chlorophyll. A ll who have worked with chlorophyll are familiar with the peculiar effects produced in solutions of chlorophyll by the action of acids. The colour is changed, and an absorption spectrum makes its appearance which differs from that of chlorophyll. According to some, these changes are due to a simple modification of the chlorophyll, others consider they are caused by the formation of products of decomposition. The latter view seems the more probable.
