The authors would like to make some corrections to their article based on some recent calculations:

The spectral resolution of IR-scanning sum frequency generation vibrational spectroscopy (SFG-VS) system can be calculated using eqn (13) in ref. 1:

where Δω_IR and Δω_Vis are the Guassian bandwidths/linewidths of incident IR beam and visible beam, respectively.

So based on our latest experiments and calculation results:

1. “Bandwidth ≈1 cm⁻¹” in the abstract (line 3) should be corrected into “Linewidth ≈1.5 cm⁻¹”.

2. “The bandwidth of the final IR beam is calculated to be ≈1 cm⁻¹, about twice the transform-limited width of a 30 ps Gaussian pulse (0.48 cm⁻¹).” in “Experimental” (page 2, left column, last third line) should be corrected into “The linewidths of the final IR beams are calculated to be ≈1.5 cm⁻¹.”

3. “The spectral resolution of the current SFG system is ≈1 cm⁻¹.” in “Introduction” (page 2, left column, paragraph 2, line 11–12) should be corrected into “The calculated spectral resolution Δν_Instr of the current SFG system is about 4.6 cm⁻¹.”
