Notes.

^(a)

Microwave lines measured between 2−40 GHz.

^(b)

Millimeter wave lines measured between 50−110 GHz.

^(c)

Millimeter wave lines reported in (Vacherand et al. 1987) between 12−64 GHz and 140−300 GHz. We excluded three lines from this reference (see text).

^(d)

Microwave lines of the AA species of the (10)p and (10)m excited states in (Niide & Hayashi 2004) measured between 12−31 GHz. The (10)p and (10)m states correspond to the (ν₁₁,ν₁₅ = 1,0) and (ν₁₁,ν₁₅ = 0,1) states, which fit with root-mean-square deviations of 48.6 kHz and 69.7 kHz, respectively.

^(e)

FIR AA species lines measured in the present work between 150−200 cm^-1, corresponding to the torsional band ν_t = 1 ← 0 (ν₁₅ torsional mode of the methyl group).

^(f)

Number of fitted lines for each set of data.

^(g)

Root-mean-square deviation for each set of data.
