UV Visible spectrophotometer works on the principle of Lambert-Beer's law which states that absorbance is directly proportional to the concentration and length of the sample cell which is usually 1cm. {eq}A=\epsilon cl {/eq} where, {eq}\epsilon {/eq}= molar absorptivit...
Explain how spectroscopy (to determine the concentration of an unknown) works in terms of molecular-level behavior.Spectrsoscopy:UV-Vis spectrophotometer uses the radiation over the ultraviolet and visible range of electromagnetic spectrum to measure the amount of...
Explain how you could Use IR spectroscopy to diffe Explain the difference between ?G and ?Go Explain the collision model. Define the term fluorescence. What are some explanations for a yield going above 100%? Activity series is a term used commonly in chemistry. What does it mean? Explain ...
d. Visible light. Infrared spectroscopy used a reversed cm-scale as opposed to UV-Vis and microwave. If 3 peaks are observed at a wavelength of 3210 nm, 3670 nm, and 3460 nm, convert these values into reversed cm used for infrar...
Fluorescence: On absorption of electromagnetic radiation, fluorescence occurs. The species undergoing fluorescence have luminescent characteristics. Fluorescence measurements can be used to analyze petroleum & byproducts. Answer and Explanation:1...
