摘要：

We draw attention to the 0.65-0.75 mu m region of the spectra of late-type M dwarfs, where we find that the TiO molecular absorption bonds decrease rather than increase in strength toward later spectral types. This decrease is not expected from synthetic spectra unless the effects of dust formation are included.
