Our original Letter presents incorrect values in the wavenumber axis of the spectra and in the spectroscopic constants. These errors do not affect the discussion and conclusion. The horizontal axes of the detachment spectra in Figure 2 of the main text and Figure S3 of the Supporting Information should be shifted as follows: Figure 2a, +5.3 cm^–1; Figure 2b, +6.0 cm^–1; Figure S3a, +5.7 cm^–1; Figure S3b, +6.4 cm^–1; and Figure S3c, −0.5 cm^–1. The revised figures are provided herein. Figure 2. Detachment spectra for probing populations of the X(v^″ = 3, 6, and 7) states (solid curves). The filled Gaussian peaks are those calculated with PGOPHER, where the width is conveniently fixed to σ = 0.48 cm^–1. The assignments are shown to the right of the plots. (a) Detachment spectrum mainly due to one-photon processes. Δv = −1 stands for an aggregate of the small contributions of the transitions 1 → 0, 2 → 1, 3 → 2, 4 → 3, and 5 → 4. The peaks of P(40) and P(42) were employed for probing the population in X(v^″ = 6), and the peaks of P(12,14,16) (band head) and P(20) were employed for X(v^″ = 7). (b) Two-photon detachment spectra overlapping with one-photon components of higher vibrational levels, measured at the storage times of 100 μs and 40 ms. The peaks of P(20) and P(24) were employed for probing the population in X(v^″ = 3). Figure S3. Detachment spectra for probing populations of the X(v′ = 0, 2, 4) states (solid curves). The filled Gaussian peaks are those calculated with PGOPHER. The assignment is shown to the right of the plots. The calculated intensities reflect time-dependent populations assuming initial rotational and vibrational temperatures to be 1500 and 4500 K, respectively. The widths are conveniently fixed to σ = 0.48 cm^–1. The arrows indicate the peaks employed for probing the population of the designated vibrational states. (a) Two-photon detachment spectra overlapping with one-photon components from higher vibrational levels. Δv = −1 stands for an aggregate of the small contributions from the transitions 6 → 5, 7 → 6, 8 → 7, 9 → 8, 10 → 9, 11 → 10, and 12 → 11. (b) Two-photon detachment spectra overlapping with one-photon components from higher vibrational levels, measured at the storage times of 100 μs and 40 ms. The counts at neighboring wavenumbers are binned together because of extremely low count rates. (c) Detachment spectrum primarily due to one-photon processes. The reference values are adopted to PGOPHER inputs unless numbers are given. From ref (1). From ref (2). In the Supporting Information, the following PGOPHER inputs (in cm^–1) should be corrected. The revised tables are provided. Table S1:

• The ground state vibronic level for v^″ = 6: 10194.08 → 10193.75
• The ground state vibronic level for v^″ = 11: 18037.39 → 18067.39

These corrections are reflected to the revised figures (Figures 2 and S3). This article references 2 other publications.
