Table 1
Rotational temperature of methanol, ethanol, g-i-propanol, a-i-propanol, Gǵ-n-propanol, and Ag-n-propanol derived from their population diagrams toward Sgr B2(N2b).
| Molecule | States(a) | Tfit(b) (K) |
|---|---|---|
| CH3OH | υ = 0, υt = 1, υt = 2, υt = 3 | 138.4 (1.7) |
| C2H5OH | υ = 0 | 133.9 (1.2) |
| g-i-C3H7OH | υ=0 | 80 (220) |
| a-i-C3H7OH | υ=0 | 110 (220) |
| Gǵ-n-C3H7OH | υ=0 | 69 (62) |
| Ag-n-C3H7OH | υ=0 | 70 (34) |
Notes. (a)Vibrational or torsional states that were taken into account to fit the population diagram. (b)The standard deviation of the fit is given in parentheses. As explained in Sect. 3 of Belloche et al. (2016) and in Sect. 4.4 of Belloche et al. (2019), this uncertainty is purely statistical and should be viewed with caution. It may be underestimated.
