The DEPT-90 spectra will show only methine (CH) peaks for carbons f, g, and h.
The DEPT-135 spectra will show methyl (CH₃) peak for carbon 'a', methine (CH) peaks for carbons f, g, and h, and the methylene (CH₂) peaks for carbons 'b' and 'c' all pointed up.

The DEPT-90 spectra will show only methine (CH) peaks for carbons f, g, and h.
The DEPT-135 spectra will show methyl (CH₃) peak for carbon 'a' and methine (CH) peaks for carbons f, g, and h pointed up, and the methylene (CH₂) peaks for carbons 'b' and 'c' pointed down.

The DEPT-90 spectra will show peaks for all the carbons.
