Indicate whether the following spectroscopic notations are allowed or not allowed, and which rule is violated for each that is not allowed. (a) 2s1 O allowed O not allowed - n too large O not allowed - / too large O not allowed too many electrons in subshell O not allowed too few electrons in subshell (b) 3s¹ O allowed O not allowed - n too large O not allowed - / too large not allowed too many electrons in subshell O not allowed too few electrons in subshell (c) 515 O allowed O not allowed - n too large O not allowed - / too large O not allowed too many electrons in subshell O not allowed too few electrons in subshell (d) 453 O allowed O not allowed - n too large O not allowed - / too large O not allowed too many electrons in subshell O not allowed too few electrons in subshell (e) 4g9 O allowed O not allowed - n too large O not allowed - / too large O not allowed too many electrons in subshell O not allowed too few electrons in subshell
Some of the most powerful lasers are based on the energy levels of neodymium in solids, such as glass, as shown in the figure. 2.1 eV 1.67 eV λ = 0.50 eV 0 eV nm Group eV Metastable second 1.17 eV (1.06 μm) (a) What average wavelength visible light (in nm) can pump the neodymium into the levels above its metastable state? = 1.06 μm First (b) Verify that the 1.17 eV transition produces 1.06 µm radiation. eV. m Ground state
1 2 The wavelength of the four Balmer series lines for hydrogen are found to be 410.5, 434.6, 486.4, and 656.5 nm. What average percentage difference is found between these wavelength numbers and those predicted by from theory) could duplicate this phenomenon. % t 1 = R(1²2² - 01/²2) ²² ? It is amazing how well a simple formula (disconnected originally
