Which molecule produces the spectral absorption bands that are prominent in the spectrum of the cool M-type star in Figure 17-12?

Question

Quizplus · Accepted Answer

The prominent absorption bands in M-type star spectra are produced by TiO (titanium oxide) molecules, making option C the correct choice. While methane (A) is present in the atmosphere of M-type stars, it does not produce the prominent absorption bands seen in the spectrum. Water vapor (B) and hydrogen chloride (D) are also present in M-type star atmospheres, but they do not have significant absorption features in the visible spectrum.
