Review from last class: $C(s{p}^3)-H3000-2800c{m}^{-1}($variable$),C(s{p}^2)-H3100-3000c{m}^{-1}($weak$),C(sp)-H3300c{m}^{-1}($strong$)$: Strong, weak, etc. refer to the strength of the adsorption, i$.$e$.\%$ transmittance $($y$-$axis$)$

IR of $1-$h$$itanol

Questions

a$)$ Give the approximate wavenumber range of the non$-$fingerprint peak that has been present in every IR so far. Which molecular vibration $($motion$)$ absorbed this frequency $($i$.$e$.,$ C$-$O stretching$)?$

b$)$ Give the range of the new non$-$fingerprint region peak that appears in the IR spectrum of $1$butanol and what is distinctive about this peak compared to other peaks you have seen?
