Is Dimethylformamide DMF suitable for UV spectroscopy detection?
Yes
What is the advantage of using UV-Vis spectroscopy compared to a spectronic 20?
Spectronic 20 was also an UV-Vis spectrophotometer.
What is ring residue in Woodward fiser rule of uv spectroscopy?
khasm twada
Why non metals are not absorbed by Atomic Absorption Spectroscopy?
Because nonmetallic elements are in vacuum UV
Why holmium oxide is used in calibration of uv?
Because Only holmium can give sharp peaks in both UV and Vis range, Sharp peak is very rare in UV/Vis spectroscopy. It is very stable and doesn't absorb light at lower wavelength.
Analysis of captopril by uv spectroscopy?
actually captopril is a PH sensative drug, as per IP-in 0.1N HCL it's showing 212nm, and it's very difficult to find out lambda by UV-spectroscopy because the UV visible range of UV- is 200-400nm, and generally near to 200nm all lambda consider as solvent pick....so UV-spectoscopy is not perfact one for analysis purpose of captopril.
What are 5 methods of analysis in chemistry?
Mass spectrometry, UV/Vis spectroscopy, NMR spectroscopy CNMR spectroscopy, Infra red spectroscopy
What are the three techniques for analysis of spectroscopy?
1 infra-red (UV-VIS) spectroscopy. 2 proton magnetic resonance spectroscopy. 3 carbon 13 magnetic resonoce spectroscopy.
Is Dimethylformamide DMF suitable for UV spectroscopy detection?
Yes
How to calculate UV spectroscopy for beta-carotene?
By the Huckel determinant
What is the advantage of using UV-Vis spectroscopy compared to a spectronic 20?
Spectronic 20 was also an UV-Vis spectrophotometer.
What is ring residue in Woodward fiser rule of uv spectroscopy?
khasm twada
What is woodwardfieser rule in uv spectroscopy?
Woodward Fieser rules are a set of emperical rules to calculate lambda max. in UV spectroscopy theoretically. They can be used to calculate the wavelength of maximum absorption of dienes and conjugated carbonyl compounds.
What does Wavelenght vs absorbance graph depicts in u-v spectroscopy?
A wavelength vs absorbance graph depicts in uv spectroscopy shows the different colored wavelenths of UV light and how they are absorbed and percieved, and which ones are visible and which ones are not.
How can you identify a unknown compound using uv spectroscopy?
Each compound has a specific absorption spectra.
Why non metals are not absorbed by Atomic Absorption Spectroscopy?
Because nonmetallic elements are in vacuum UV
How do you calculate the particle size in UV-vis spectroscopy?
you can determine the size of nanoparticles from UV-VIS spectroscopy. it is also comparable with TEM analysis.with below formula you can determin ethe size of nanoaprticles. d = Ln(landa SPR- landa0)/L1/L2
