Notes.

^(a)

Frequencies and energies were acquired from the CDMS database (Müller et al. 2001), except for the c-C₃H₂ data, which are from the JPL database (Pickett et al. 1998).

^(b)

F₁ = 1–0, F = 0–1.

^(c)

Blend of F₁ = 3–2, F = 4–3; F₁ = 3–2, F = 3–2; and F₁ = 3–2, F = 2–1.

^(d)

This is a blend of two c-C₃H₂ lines.

^(e)

Only SMA data are available for these lines.

^(f)

Blend of F = 5/2–3/2, F = 7/2–5/2, and F = 3/2–1/2.

^(g)

F = 3/2–3/2.

^(h)

F = 5/2–5/2.
