How can detect free radicals by ESRA spectroscopy?
It is possible to detect free radicals by ESR spectroscopy and imaging through the use of nitroxides. ESR stands for Electric Spin Resonance. Nitroxides trap free radicals under the skin during UV irradiation.
What is metastable ion in mass spectroscopy?
An ion that is formed with sufficient excitation to dissociate spontaneously during its journey from source to detector is called metastable ion.
What is the difference ultraviolet and infrared spectroscopy?
FTIR spectroscopy cannot be used to detect all the vibration modes in a molecule. It can be used only to study the non-symmetrical vibrational state in an atom. Using Raman Spectroscopy one can study the symmetric stretch of the atom. For example the symmetric stretch of CO2 which cannot be studied by FTIR can be studied by Raman Spectroscopy. Here the permanent dipole moment of the molecule during a vibrational cycle does not change as it does not involve polarization. As a result, this mode cannot absorb infrared radiation. In many instances, vibrational modes that are not observed by infrared absorption can be studied by Raman spectroscopy as it is the result of inelastic collisions between photons and molecules
Gregor Mendel did his research during the middle part of what century?
the 19th century
What are the important developments in the field of chemistry during the 15th century?
Scientific instruments Medicine Chemistry
What is European feudalism?
European feudalism emerged when the Roman empire fell during the 5th century. During the 10th century, it was in France and Germany that the first elements of feudalism appeared.
What is the educational system during 19th century in the Philippines?
During the 19th century in the Philippines, education was primarily controlled by the Spanish colonial government. It was geared towards instilling Catholicism and Spanish culture among the natives. Only the elite and wealthy families had access to formal education, which was usually conducted in Spanish. Indigenous forms of education, such as the "escuelas pias" and "tribal schools," still existed but were marginalized compared to the Spanish educational system.
Homer's identification and achievements?
Homer was a Greek poet. He wrote both the poems The Odyssey and Iliad. He lived during the 8th century BCE, while the Trojan war is dated to the 12th century BCE.
During which century did the year 1645 occur?
During the 17th century.
During which century did the year 1945 occur?
During the 20th century.
