Applications of Molecular Spectroscopy

When light sources pass through the diffraction grating then light splits into different wavelengths. The light source produces two types of patterns that are shown as destructive and non-destructive. The light source is in the form of quanta that is quantitation.

Chemistry In my picture, I used NaH to "deprotonate" the hydroxyl groups in my cellulose monomers in order to ionally attach positively charged lipids to make it a waterproof "T-shirt". However, I believe the NaH is too strong of a base, and in reality it would deprotonate all the hydroxyl groups and ruin the intermolecular hydrogen bonds. Which base should I use instead in order to preserve the intermolecular hydrogen bonding? I only want to deprotonate the surface to attach the lipids, as demonstrated in the picture.

When dissolved in water, flunitrazepam, also known as roofies or the "date rape" drug, is difficult to detect because it is colorless, odorless, and tasteless. Recently, a straw has been developed that changes color when placed in a drink spiked with flunitrazepam. A woman at a bar is worried that flunitrazepam was slipped into her water when she left it unattended. She places one of these new color-changing straws into the water and the straw does not change color. Based on this result, is the woman's drink a pure substance or a mixture? mixture pure substance If it is a pure substance, is it an element or a compound? compound
