- adj. (Chem.) Having the same chemical composition and molecular weight; having the same number of atoms of each kind in the molecule; -- said of chemical compounds with known chemical composition. This property used to be called
metamericto distinguish it from other forms of isomerism.
- adj. of or relating to or exhibiting isomerism
“The chemist is acquainted with numerous groups of substances which we call isomeric compounds, and two substances are said to be isomeric when they not only consist of the same elements united in the same proportions, but also have the same density in the state of vapor, so that according to the molecular theory their molecules must have the same weight.”
“Technetium-99m decays by a process called "isomeric"; which emits gamma rays and low-energy electrons.”
“When we dissolved CpdA in PBS (pH = 7.6) or Tris-HCl buffer (pH = 7.6) rapid formation of two reaction intermediates occurred, which we could identify as the isomeric forms of N-methyl-2 - (4-acetoxyphenyl) - aziridine (”
“Together they provided the first indication of an isomeric state in Carbon”
“Perhaps the most famous creation of an isomeric compound was Wöhler's accidental synthesis of urea in 1828, when he was attempting to prepare ammonium cyanate (which he later succeeded in preparing by allowing the crystals to form at room temperature instead of by evaporating the solution).”
“Not only is manufactured CLA not as good as natural, some of the factory-made stuff is in an isomeric form that has been shown to be detrimental to health.”
“Perhaps one codon codes for one isomeric form of an amino acid, and another codes for a different isomeric form of the same amino acid.”
“Various groups have tried to reproduce this experiment, and various panels of scientists have spoken of the unfeasibility of this avenue of investigation as a viable weapons program …. but still the research gets support, the goal being a so called “isomeric bomb”.”
“In the case just now assumed we arrive at the oxychloride; when, however, the metal and chlorine change places in the water molecule, the isomeric hypochlorous salts are the result.”
“They also employed isomeric mixtures of the gases; methylic ether, cyanogen, hydrogen, acetylene, and other gases were experimented upon, and the general conclusions are as follows: 1.”
