Nanoscopy techniques sush as STED and MINFLUX

High Resolution Transmission Electron Miscrospy (HRTEM)

The smaller interval (distance) that can be observed or measured with a micriscope

The capability of distinguishing peak positions in vibrational spectra

The agnification that can be obtained in a microscope

The ability to distinguis objects that are very small or tell them apart if they are too close thogether

A firm decision (like those mmade on New Yer´s Eve) to learn microscopy

Obtein exactly the same information as FTIR for any organic molecule

Do routine measuremts of the elemental composition of a sample

Determine what functional groups are present in an organic molecule

Identify some inorganic compounds

Identify organic compouns or biomolecules in aqueous solitions

Analyze samples inside opaque containers

Laser have very specific wavelengths, narrower than the bandwidth achievable with a monochromator

The number of photons that are emitted after Raman excitation is very small

The absorption cross-section is very small because the bonds have to be polarizable for the raman signal

The number of photons that undergo Raman scattering is very small ( 1 in 10^7)

Know how many ohotons (H) are in each of a different type of functional group

Distinguis between isomers

Determine the elemental composition of a compound

Analyze the purity of a compound

Determine the structure of organic molecules, i.e. the functional groups and to what other part of the molecules they are bonded
