implies either 2 double bonds, 2 rings or 1 double bond and 1 ring. and so on.So this formula isn't too useful unless you have extra information that would allow you to eliminate the chance of rings - meaning that the number will be just the number of double bonds.If we were given...
The double bond equivalent, DBE, represents the number of pi bonds or rings in an organic molecule. It gives information on the unsaturated sites in a molecule. Some other names for DBE are: Degree of unsaturation (DoU); Unsaturation index (UI); or Index of hydrogen deficiency (IHD). The...
Aromaticity index (AI) and double-bond equivalent (DBE) were studied to seek a simpler approach in identifying suitable ionic liquids for the desulphurization process. Manifestation of interaction mechanism by COSMO-RS and Raman spectroscopy is discussed. The findings demonstrate that AI and DBE calcu...

Exchange Note Issuance Datehas the meaning stated in Section 2.2(a)(i) of the Exchange Note Supplement. Stock Issuance Agreementmeans the agreement entered into by the Corporation and the Participant at the time of issuance of shares of Common Stock under the Stock Issuance Program. ...
Or what if the household had money invested in the stock market and it was a bad year, meaning they lost money or maybe broke even. The government would still demand $1,200 of tax even though there were no earnings. That’s means a tax rate for higher than 100 percent. Infinite! Bar...

One has to note that the term 11-bond has a somewhat different meaning in linear and in planar molecules (20). We further remind the reader that 02 has an open-shell configuration and hence, in con-formity with Hund's rule a triplet ground state, whereas both c2 and c2H4 have closed...
The EMR methods only detect magnetic interactions within a few angstroms of the electron spin, meaning that one can characterize the small pocket of the system that is of chemical interest. The modern computational procedures that enable one to perform calculations on many electron systems, the...
The invention relates to a process for the preparation of a ketone from a tertiary alcohol having a double bond in the alpha position, that includes the step of contacting tertiary alcohol having a double bond in the alpha position with ozone in the pres
