	abstract = {In an earlier paper we modeled the far-infrared emission from a 
star-forming galaxy using the photoionisation code CLOUDY and presented
metallicity sensitive diagnostics based on far-infrared fine structure
line ratios. Here, we focus on the applicability of the
[OIII]88/[NII]122 microns line ratio as a gas phase metallicity
indicator in high redshift submillimetre luminous galaxies. The
[OIII]88/[NII]122 microns ratio is strongly dependent on the ionization
parameter (which is related to the total number of ionizing photons) as
well as the gas electron density. We demonstrate how the ratio of
88/\$122 continuum flux measurements can provide a reasonable estimate of
the ionization parameter while the availability of the [NII]205 microns
line can constrain the electron density. Using the [OIII]88/[NII]122
microns line ratios from a sample of nearby normal and star-forming
galaxies we measure their gas phase metallicities and find that their
mass metallicity relation is consistent with the one derived using
optical emission lines. Using new, previously unpublished, Herschel
spectroscopic observations of key far-infrared fine structure lines of
the z{\textasciitilde}3 galaxy HLSW-01 and additional published measurements of
far-infrared fine structure lines of high-z submillimetre luminous
galaxies we derive gas phase metallicities using their [OIII]88/[NII]122
microns line ratio. We find that the metallicities of these z{\textasciitilde}3 submm
luminous galaxies are consistent with solar metallicities and that they
appear to follow the mass-metallicity relation expected for z{\textasciitilde}3 systems.},
