Sketch the forms of the following solution phase NMR spectra (abundances shown as per cent):

(a) The ¹H-NMR spectrum of KBH₄

(b) The ¹H- and ¹⁹⁵Pt-NMR spectra of cis-[Pt(CO)₂(H)Cl] ¹H, I = ½, 100 per cent; ¹⁹⁵Pt, I = ½, 34 per cent; ¹⁰B, I = 3; 20 per cent; ¹¹B, I = 3/2; 80 per cent; no other nuclei contribute to these NMR spectra.
