The 13C NMR spectrum of ethanoic acid (acetic acid) shows a quartet centred at δ = 21 with a splitting of 130 Hz. When the same spectrum is recorded using proton decoupling, the multiplet collapses to a single line. Another quartet, but with a much smaller spacing, is also seen centred at δ =178; this quartet collapses when decoupling is used. Explain these observations.
12D.15 At low resolution, the strongest absorption band in the infrared absorption spectrum of 12C¹6O is centred at 2150 cm-¹. Upon closer examination at higher resolution, this band is observed to be split into two sets of closely spaced peaks, one on each side of the centre of the spectrum at 2143.26 cm-¹1. The separation between the peaks immediately to the right and left of the centre is 7.655 cm-¹. Make the harmonic oscillator and rigid rotor approximations and calculate from these data: (a) the vibrational wavenumber of a CO molecule, (b) its molar zero-point vibrational energy, (c) the force constant of the CO bond, (d) the rotational constant B, and (e) the bond length of CO.
