Scientific paper

A sample of 14 small Bok globules and of eight Herbig Ae/Be stars has been observed in the molecular rotational lines of HCO+, HCN, HNC, N2H+, and C2H at 3 mm wavelength. The observational results have been used together with a pseudo-time-dependent chemical model to study the evolution of a molecular cloud toward the formation of a low-mass star. The new chemical and physical scenario that is inferred from the molecular line data is discussed in relation with the existing literature data obtained from infrared to far-infrared data.
