Isomers

Substances which have precisely the same chemical formulæ (called isomers) have properties as widely apart as alcohol and ether. ❋ John Burroughs (1879)

Both of the following have four carbon atoms and ten hydrogen atoms they are called isomers ❋ Skyash (2009)

These and similar substances, called "isomers," led chemists to suspect that substances are defined not simply by the number and kind of atoms in the molecule but also by the arrangement of those atoms. ❋ Unknown (2007)

The results, Bada said, were even more remarkable than the earlier experiments—with a greater number of amino acids produced and a better lineup of isomers, compounds with the same molecular formula but with different structures. ❋ Marc Kaufman (2011)

Not only was he able to purify highly concentrated carotene, but in early 1931 he succeeded in separating two similar but distinct forms (isomers). ❋ Unknown (2010)

Sometimes, Mrs. Janner, it is important to remember that life is an isomerism in which the isomers change into one another with great ease so that they ordinarily exist together in equilibrium. ❋ Jeffrey S. Callico (2011)

They then demonstrated that the different isomers of carotene have a qualitatively identical effect on the growth of the rats, their sexual cycle and a number of diseases. ❋ Unknown (2010)

Kuhn and Lederer called these isomers beta - and alpha-carotene. ❋ Unknown (2010)

Kuhn, Lederer and Winterstein turned to detailing the compositional differences between the different isomers. ❋ Unknown (2010)

Cardioprotection with palm oil tocotrienols: comparison of different isomers. ❋ Craig Cooper (2011)

These include advanced nuclear processes, such as fusion, hot isomers, low energy nuclear reactions and combined fission/fusion concepts. ❋ Unknown (2008)

As observed in all consequent experiments, both left-handed (L) and right-handed (D) optical isomers were created in a racemic mixture ❋ Unknown (2008)

This time lagg between the production and absorption spectroscopy can lead to formation of different isomers of ClO, with totally different optical properties. ❋ EliRabett (2009)

TCP is much more dangerous than first realized because it contains neutotoxic. isomers, tri-ortho-cresyl phosphate (TOCP), MOCP (mono-ortho-cresyl phosphate) and ❋ Unknown (2009)

While this document is specifically focused on the primary forms or isomers of DDT, DDE, and DDD (namely p, p'-DDT, p, p'-DDE, and p, p'-DDD), other isomers of these compounds will be discussed when appropriate. ❋ Unknown (2008)

That reminds me a *lot* of hydrocarbon isomers, for some reason. on 10 Jan 2008 at 1:15 pm2Randy ❋ Unknown (2008)

Two, and you get xylene, which comes in three isomers, meta, para, and ortho, depending upon whether the methyl groups sit right next to each other (ortho), on opposite sides of the ring (para) or one over (meta). ❋ James Killus (2008)

Next week, I have to teach the class about isomers and isotopes. ❋ Clare B. Dunkle (2008)
