FACTS YOU NEED TO KNOW ABOUT NUCLEAR MAGNETIC RESONANCE

-

1. It is concer ned with the magnetic properties of certain nuclei,notably the nucleus of the hydrogen atom. 2. Studying an organic molecule by NMR spectroscopy enables us to record difference in the magnetic properties of the various nuclei present and to deduce in large measure what are the positions of these nuclei within the molecule. 3. We can, for proton NMR, deduce how many different kinds of hydrogen environments that are in the molecule and also which hydrogen atoms are present in neighbouring carbon atoms. 4. It has been found and hat nuclei with even atomic numbers and even mass numbers does not exhibit NMR. e.g Helium -4, Carbon -12 and Oxygen -16.

WHAT YOU NEED TO KNOW ABOUT ADSORPTION OF GASES BY SOLIDS

-
Image
The phenomenon of adsorption should not be confused with adsorption which refers to one material passing into the bulk of another. For example, water is adsorbed by a sponge and water vapours are adsorbed by anhydrous calcium chloride. The term Sorption is used which includes both adsorption and absorption like the process where water vapours are adsorbed by silica gel and acetic which is. adsorption or absorption. When solids are allowed to remain in contact with a gas, a film of gas molecules accummulates on the surface. Solid and liquid surfaces, therefore, have a tendency to satisfy their residual forces by attracting onto and retaining on their surfaces, molecules of gases or other substances with which they come in contact. This results in higher concentration of molecules on the surface of a solid or liquid than in the bulk of the medium. This phenomenon is known as ADSORPTION. The substance in which the adsorption takes place is know ADSORBENT and tye substance whic

Simi and Adekunle Gold reportedly arrived the US long before the coronavirus pandemic. Read the report below… “Musicians Simi and Adekunle gold who are currently in the US welcomed their baby many weeks ago according to sources based in the US…. The couple who arrived the US before the Coronavirus pandemic lockdown to birth their baby have been locked down there since the arrival of their patter of tiny feet. Insiders reveal that Simi had birthed her baby long before the Duduke challenge she started on Instagram…*wink* Their baby news is heavily coded and i suggest we wait for them to announce the gender and the date of arrival themselves…. Congratulations to Simi and Adekunle.”

All you need to know about mass spectrometry and the fragmentation rules

-
Image
A mass spectrometer consists of three components: an ion source, a mass analyzer, and a detector.  The  ionizer  converts a portion of the sample into ions. There is a wide variety of ionization techniques, depending on the phase (solid, liquid, gas) of the sample and the efficiency of various ionization mechanisms for the unknown species. An extraction system removes ions from the sample, which are then targeted through the mass analyzer and into the  detector . The differences in masses of the fragments allows the mass analyzer to sort the ions by their mass-to-charge ratio. The detector measures the value of an indicator quantity and thus provides data for calculating the abundances of each ion present. Some detectors also give spatial information, e.g., a multichannel plate. A mass spectrum is a plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or  isotopic signature  of a sample, the masses of particles
