The region below ~ 1600 cm-1 (the right-hand side of the IR spectra, perticularly from about 1500 to 500 cm-1) usually contains a very complicated series of absorptions. This region is fingerprint region.
These absorptions are basicaally due to all manner of bending vibrations within the molecule.

Many ancient tombs were cut from limestone rock that contained uranium. Since most such tombs are not well-ventilated, they may contain radon gas. n one study, the radon levels in a sample of 12 tombs in a data, assume that x 3,608 Bq/m and s 1,138 Bq/m. Use this information to estimate, with 95% confidence, the true meae level ef radon exnosure in tombs in the region. Interpret the resulting interval The confidence interval is (Round to the nearest integer...
