Column density ratios of alkanols and alkanethiols in different sources.

	MeOH	MeSH	MeOH	EtOH

Source	EtOH	EtSH	MeSH	EtSH

Sgr B2(N2)	20	≳21	118	≳125
Orion KL^a^,^b	31	5^c	120	20^c
G327.3−0.6^a^,^d	82		58

Notes.

^(a)

Methanol (MeOH) inferred from ¹³CH₃OH. EtOH, MeSH, and EtSH short for ethanol, methanethiol, and ethanethiol, respectively.

^(b)

Orion KL data from Kolesniková et al. (2014)

^(c)

Only for gauche-EtSH; ratio would be smaller by about a factor of 1.25 with anti-EtSH assuming LTE.

^(d)

G327.3−0.6 data from Gibb et al. (2000).
