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...
Chemistry(GeneralAromaticity 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 ...
This bond is acovalent bondmeaning that carbon shares its outer valence electrons with up to four hydrogens. This completes both of their outer shells making them stable. ... Using Pauling's scale—C (2.55) and H (2.2)—the electronegativity difference between these two atoms is 0.35. Is ...

In the DLM model, thermal perturbations are introduced, assuming that the magnetic moments in the system are disordered, meaning that the magnetic moment of each atom is assumed to be random. This allows us to obtain the electronic structure and energy distribution in the disordered magnetic state...
they’ve taken to texting each other a photo every once in a while—message-free, just a random image from one of the day’s quiet moments. One might speak of how mindfulness, a certain quality of presence, can touch a small gesture like this with meaning. But Brooks says the practice...
In the metathesis reaction according to the invention, 1 mol-equivalent of this trans-alkene liberates 2 equivalents of a reactive intermediate (which may also be rewritten as “R11-[-A11-]a-[-Z11-A12-]b-Z12-CH═”) with breaking of the central C═C double bond, and this intermediate...
In one aspect, the present invention provides isolated nucleic acid molecules that each: (a) encode an aryl propenal double bond reductase; and (b) hybridize to a nucleic acid molecule consisting of the complement of the nucleic acid sequence set forth in SEQ ID NO:1 under defined conditions...
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
