Abstract
With the 30-m IRAM radio telescope, we observed several massive star forming regions at wavelengths of 3–4 and 2 mm. The temperature of the gas in the sources was estimated from the lines of CH3CCH and from the transitions of the NH3 molecule obtained during observations at the 100-m radio telescope in Effelsberg. As a result, a correlation between the integrated intensity ratios of the J = 1−0 transitions of H13CN–HN13C and the kinetic temperature has been obtained. The obtained results allow us to propose the use of the intensity ratio H13CN–HN13C as a possible temperature indicator of interstellar clouds. We also compared the obtained estimates of the kinetic temperature with the dust temperature $${{T}_{{{\text{dust}}}}}$$ . As a result, no significant correlation was found.
