In this work, we study the infrared dust bubble N75 and the infrared dark cloud G38.93 mainly using the tracers C18O, HCO+ , HNC, and N2H+ observed by the 30m IRAM telescope. We also study the targets using data from large-scale surveys: GLIMPSE, MIPSGAL, GRS, NVSS, and BGPS. We found that the C 18 O emission is morphologically similar to the Spitzer IRAC 8.0 µm emission. The 1.1 mm cold dust emission of G38.93 shows an elongated structure from southwest to northeast. The ionized gas from G38.93 is surrounded by the PAH emission, which may be excited by radiation from G38.93. We found that the identified YSOs tend to cluster around G38.93 and mostly in class II, with several class I distributed around N75, but noclass II. We also found evidence of expanding feedback, which could have triggered starformation.
