In organic chemistry, an auxochrome () is a group of atoms attached to a chromophore which modifies the ability of that chromophore to absorb light. They themselves fail to produce the colour, but instead intensify the colour of the chromogen when present along with the chromophores in an organic compound. Examples include the hydroxyl (), amino (), aldehyde (), and methyl mercaptan groups ().

Typically, this will be the removal of water from a solution or suspension, such as the removal of water from fruit juice.

In chemistry, dimerization is the process of joining two identical or similar molecular entities by bonds. The resulting bonds can be either strong or weak. Many symmetrical chemical species are described as dimers, even when the monomer is unknown or highly unstable.
