The time-resolved infrared emission spectrum of Cu was recorded in the 1800-3800 cm(-1) spectral region with a resolution of 0.017 cm(-1). The time profiles of the measured lines have maxima at 18-20 mu s after a laser shot and display non-exponential decay with a decay time of 5-15 mu s. This study reports 17 lines (uncertainty 0.0003-0.018 cm(-1)) of Cu I not previously observed. This results in seven newly-found levels and revised energy values for 11 known levels (uncertainty 0.01-0.03 cm(-1)). We also calculate transition probabilities and oscillator strengths for several transitions involving the reported Cu levels.
