to 18 000 [cm$^{-1}$]{}, will be used as the starting point for a semi-empirical fit of the PES. This should give a line list which is both more accurate and more extensive than BYTe.

CrH
---

Chromium hydride is an important astronomical molecule for a variety of reasons, including classification of brown dwarfs [@99KiReLi.CrH; @jt430] and measurements of magnetic fields [@13KuBexx.CrH]. The ExoMol database currently provides a substantially empirical line list due to Burrows [[*et al*]{}]{}[@02BuRaBe.CrH]; we are in the process of computing a more complete CrH line list covering 8 states and the 4 main isotopologues [@jtCrH].

TiH
---

The current titanium hydride line list due to Burrows [[*et al*]{}]{}[@05BuDuBa.TiH] is in the process of being updated with a more extensive ExoMol one.

Other species
-------------

Besides the species listed above, line lists are in an advanced stage of construction for VO [@jt621], H$_2$O$_2$ [@jtHOOH] (see Al-Refaie [[*et al*]{}]{}[@jt620] for a preliminary, room temperature version), SO$_3$ [@jtSO3] (see also Underwood [[*et al*]{}]{}[@jt554]), C$_2$H$_4$, CH$_3$Cl (see also Owens [[*et al*]{}]{} [@jt612]), C$_2$, SiH, NS, NO, NaO, AlH and SH [@jtAlH], MnH, and PO, PS and PH [@jtPS].

Finally we note that work is in progress looking at TiO [@jtTiO]. TiO
