The authors regret that there were multiple errors in the original article.

There was an error in Table 1 where column 4 row 2 reported the same value as column 5 row 2 (3.6 au), instead of the correct one (1.206 au). The correct version of Table 1 is presented here.

Table 1 Vibrational spectroscopic data of H₂O and D₂O, from ref. 54. ϖ₀: peak frequency, expressed in wavenumber; ε₀ molar absorption coefficient; A_{10 μm}: absorbance for a 10 μm pathlength; l_opt: optimal path length, at which the S/N ratio is maximized. ν_S: symmetric stretching mode; ν_AS: antisymmetric stretching mode; δ: bending mode; δ + η: combination bending and libration mode

Vibrational mode	ϖ0/cm^−1	ε0/M^−1 cm^−1	A10 μm/au	lopt/μm
νS, H2O, νAS, H2O	3404.0	99.9 ± 0.8	5.53	0.8
δH2O	1643.5	21.8 ± 0.3	1.206	3.6
δ + ηH2O	2127.5	3.50 ± 0.1	0.194	22.4
νS, D2O, νAS, D2O	2504.0	71.5 ± 0.4	3.94	1.1
δD2O	1209.4	17.4 ± 0.2	0.962	4.5
δ + ηD2O	1555.0	1.91 ± 0.05	0.105	41.2

There is also an error in a sentence in the section “Qualitative analysis: detection of analytes in static samples” on page 3228 of the original article. The sentence “Most of these applications were performed using a conventional global light source, …” should be replaced with “Most of these applications were performed using a conventional thermal light source, …”.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
