Dense gas in molecular cloud cores is essential in researches of extragalactic star formation (e.g. Solomon, Downes, and Radford). To determine the physical relations between star-forming regions and dense gas, we have observed CS (J=3→2) in starburst galaxies M 82 and NGC253. The J = 3 level of CS is 14.1 K and the critical density for excitation is 4 × 105 cm−3.
