The intramolecular isomerisation, a 1,3-sigmatropic reaction, is unfavorable because an antarafacial mode is enforced.

All the camphor sunscreens are supposed to dissipate the photon energy by cis-trans isomerisation.

Early in 1992, we commissioned the new $130-million isomerisation plant at our Lavera refinery in France, on time and under budget.

(i) isomerisation.

Enthalpy changes also accompany the transformation of one allotrope to another (see section 3.2) and the process of isomerisation (see section 17.1).

The trans- form can undergo isomerisation to the cis- form when exposed to ultraviolet irradiation, a process called photoisomerization.:

Isopentane solutions of barrelene undergo photolytic isomerisation when acetone is added as a photosensitizer to produce semibullvalene.

The large energy barriers between these structures do not make isomerization possible.

This isomerization can also lead to motion on larger length scales.

The two forms must undergo isomerization with each catalytic turnover.

The energy difference between two isomers is called "isomerization energy".

In some cases, very subtle structural differences dictate the favored direction of isomerization.

One such reaction is the isomerization of meta-xylene to para-xylene.

The isomerization of normal paraffins does not consume or produce hydrogen.

The quantum yield of isomerization can be strongly dependent on conditions (see below).

The first stage involves isomerization, however high temperature accelerates the radical processes.

This size-selectivity allows the isomerization reaction to occur quickly in high yield.

In some molecules and under some conditions, isomerization occurs spontaneously.

Double-bond isomerization may occur upon treatment with base as shown in equation (3) below.

Longer boil times will result in isomerization of more of the available alpha acids.
