How the bond angle of a water molecule is measured?

WebA bond distance (or bond length) is the distance between the nuclei of two bonded atoms along the straight line joining the nuclei. Bond distances are measured in Ångstroms (1 Å = 10 –10 m) or picometers (1 pm = 10 –12 m, 100 pm = 1 Å). Figure 5.2.1: Bond distances (lengths) and angles are shown for the formaldehyde molecule, H2CO. WebAnswer (1 of 3): How else but by measurement? Of course, the actual measurement may be not so straightforward. Upon crystalline compounds, X-ray crystallography may be performed, and this gives reams of data with regard to bond lengths and bond angles. For gases (and some liquids) IR spectroscopy...
